"The Z28 frame brackets are different heights to compensate for the additional thickness of the antilift bracket, their difference is exactly the thickness of the bracket."

Here is my opinion on the frame stand height difference...

This, I believe, is merely a coincidence, as the retrofit was more than 2/3 of the way through 1969 production.

Why, if the safety stop was taken into consideration when the frame stands were designed, were they not installed until after 9-10 months of production? 

Hi James,

You might very well be correct, never thought about it that way. I have changed lots of engines in first gens in the last 40 years and I have never had trouble getting the engine to sit level, but I guess that is why both engine frame stands are slotted. I probably just assumed the hite difference was because of the antilift bracket, mainly because of this post. I ran a Corvette/Camaro restoration shop for 18 years (1987-2005) and I have only seen these anti lift brackets a few times, last 1 was in a 69 Corvette 350/300hp car.
 It would be interesting to know how many cars originally had them, I wonder if lots of them were removed under the engine mount recall program.
 The mystery continues.


107  Camaro Research Group Discussion / Restoration / Re: Sway Bar End Links - Correct Finish & Bushings on: February 26, 2011, 04:50:20 PM
Are all components of the front sway bar end links (bolts, nuts, washers & spacers) supposed to be silver zinc or cad?  I can't tell from my original parts.

Also, does anyone know where to get the correct end link bushings?  My original bushings are slightly taller and a different shape than the generic replacement style bushings.  These look like the correct bushings, but only appear to be available as part of a kit:

AMK has them, and they have the same smudge/ink ?  marks as the heartbeat ones. I just got some and they are identical. $4 for 4, you need 8 BTW.

The big block frame stands are different to offset the engine to the right . I was wanting to know if the rubber mount was different on the left to allow for the anti lift bracket thickness .

Not sure on the big block mount but the small block rubber mounts I posted pictures of, are the same hite.
109  Camaro Research Group Discussion / Originality / Re: Original long bolts for 1969 L/78 motor mounts on: February 26, 2011, 02:44:10 PM
Thanks . does any one know if on a big block if the rubber mount is thinner with the bracket ?

I think Steve shows that the 396 RH frame mount is taller on page 1 of this post, I think all the engine insulators are the same physical height, the anti lift bracket thickness is equalized by the frame mounts.
110  Camaro Research Group Discussion / Originality / Re: Original long bolts for 1969 L/78 motor mounts on: February 26, 2011, 12:23:23 AM
Is the mount that uses these brackets shorter than a regular mount to allow for the thickness of the bracket , or does the engine set higher ? How thick is the bracket ?

The Z28 frame brackets are different heights to compensate for the additional thickness of the antilift bracket, their difference is exactly the thickness of the bracket. Here are some shots of my Z28 mounts with a Heartbeat Repo antilift bracket. Hope this helps.

paceme,

Thanks for posting, your mounts look the same as my original Z28 mounts, except mine have RBW bolts.

 I am still puzzled by the AIM  (Z28 page) and bracket shown on page 1 of this post.  The mount appears to be different, unless it is just a generic drawing, it also shows the bolt going in from the front.

Never Mind, I answered my own question tonite. I was looking in my own AIM and mine shows the bolt going from the back on the drivers side mount, there is a revision on my page.

If you look closely at all the engine mount illustrations and pay attention to the change dates in the title block, you'll see that ALL the engine-side mounts for L-34/35, L-48, L-78, and Z/28 were changed between 5/29/69 and 6/2/69, and the base V-8 mounts were changed on 8/6/69. Cars built before that ALL had different old-style mounts.

Thanks John, So if I am understanding correctly the mounts shown that I posted were used until 6/2/69? ( June?)

 FWIW - I just put a set of GM NOS Louvers on a 02B Z28 and to my horror the drivers side hung out. Took it back off and there was a bunch of casting type flash on the back. I roloxed it down slightly and it now fits perfect.

OOPS, Just looked and they are RSC. Sorry for any Confusion.

RE: The top mount in this NEW set of photos. Is this the 69 HP Small Block Left hand (drivers) motor mount?
Shauger's L48 RS/SS with 14k miles has the original mounts on it. The right is the same as the photos above, however my photos do not clearly show the left one. I requested in the Yenko boards, however it would be great if someone could get some photos of his.


Yes this is the HP 302 left hand mount. What is weird is that if you look at the AIM sheet it shows that a bolt is used from the front and threads into the mount. This mount has the bolt comes in from the back and threads into a nut that is part of the mount.
 Unless there are 2 different mounts 1 for the antilift bracket shown above and another version. It appears that if a person used the Big Block Bracket it would work with this mount. HuhHuhHuhHuh??
117  Camaro Research Group Discussion / Originality / Re: 1969 Fuel Door Bolts.. on: February 11, 2011, 12:15:16 AM
I am currently restoring a 02B Los Z28 and my own Z28 is a 06A Norwood Z28, both have 1/4unc bolts, 7/16" wrench size, both have RBW head markings. The 06A is 100% original for sure, I have owned it since 73, 42,000 mile survivor.

Hope this Helps. Mike.

The 1969 z/28 left side mount is different then the right. My very original 11d 69z never had the engine removed. So I know the mount is original to the car.Only one other person that I know has one of these mounts. He also restored a very original car and the mount is the same as mine. John Allouez Restorations

Quote - So sorry to all the Z/28 & L/48 guys here.  Until I got into the research on this topic, I didn't know that the these cars used a similar stop bracket.  Odd that
a thru bolt and nut assembly was used on the Z & SS and the big block used the threaded receiver.  Are there any Z/28 or L/48 owners here that can post images of
their motor mount components?  I'd like to see them for comparison purposes.

OK, Here you go. I am missing the bracket and spacer.

Hope this helps. Mike.

Jerry, Wow, what a difference, the first picture of the stamp on Ebay makes the leg of the 7 appear straight but NOW the 7 FONT Looks EXACTLY the Same as all posted and Correct. ORIGINAL IMO.

Good Luck with your auction.

 Mike Thorpe.
120  Camaro Research Group Discussion / Originality / Re: "837" Alternator on: February 10, 2011, 12:40:55 PM
My own 06A Z28 original alternator is dated 9E23 as well and it does share ALL the same anomalies. My stamp looks like the 2 that Jerry has posted in this link. The 00 are faint as well as the 837 being heavy and the bottom half of the first 7 is faint.
What puzzles me about the ebay alt is the last 7 font, (in the 37A stamp) looks different to mine and the ones that Jerry Posted. The leg appears straight. I suppose that there was different characters used from time to time.
I personally think the ebay alternator is real.
 I have owned my Z28 since 1973, 42,000 mile Survivor and the alternator is with out a doubt 100% original, it still has the CZ ink stamp very faintly just behind the date stamp on the alternator back half.
