I found one under the back seat of a 1968 LOS Firebird that I had. Not that uncommon for LOS, I believe. I also found one in my Norwood built 1979 Z28 but I guess a lot changes in a plant in 10 years.
I still see them in new Buicks and GMCs taped to the seat or in the trunk and they go in the trash.

Originality / Re: Identifying 3961398 Oil Pan, 1969 302 Production line?
« Last post by z28z11 on February 22, 2017, 02:21:01 AM »
By the time the pans hit the parts counters, the 3974251 pans might have been the only NOS part number available at that time, as the date on my installation instruction notes - 2/69. Pretty early in the production to change the part number, so finding one of the NOS 3961398 pans might be nigh unto impossible.

I've got three pans - my original production line pan, the 251 pan, and a 465220 I bought for the MO assembly I did for the '68. The 465220 pan has a very narrow front seal lip, different radius, too - I need to revisit the old threads concerning FelPro one piece seals and rebutton this one before it goes into the car. Hate leaking anything, especially oil pan gaskets.

Mild Modifications / Re: Original steel brake lines or stainless steel. Preferences?
« Last post by z28z11 on February 22, 2017, 02:06:08 AM »
Search the threads and get ready for an avalanche of discussion. Some people have had difficulties with stainless lines sealing at the threaded connections, other say they are great and have had no problems at all. I have a complete set for my X77 in stainless, acquired many, many years ago - I'm determined to make them work. I did salvage the original lines for the most part, may try steel lines on the next one (Pace Car refresh, still originals).

Mild Modifications / Original steel brake lines or stainless steel. Preferences?
« Last post by little_hoss on February 22, 2017, 01:54:52 AM »
Just looking for some opinions on which ones anyone has used or their preferences. Getting ready to swap my 67 over to power front disk brakes and going to get all new lines front to rear and on up to the master cylinder. Just looking for some input or thoughts on the subject. Planning to use original spindles and brackets along with single piston calipers from a 69 I acquired a number of years ago. Other than the calipers, would like to make it look factory stock for 1967. Any comments are appreciated! Thanks!

I also owned a '70 LS5 Chevelle up until 2011 - during my attempt to sell it on eBay, some kind enthusiast let me know that Atlanta built Chevelles like mine had the broadcast copy glued to the back of the door panel (the only place I had not looked for it). To my very great relief, the copy was right there, absolutely perfect condition, glued very firmly to the door panel, with every last detail including the shipping info, dealer code, dealer and LS5 documentation that I needed to prove out the car: the dream of all of our collective Norwood production fellow Camaro owners. Although I have the dealer invoices on two of my Camaros (luckily the '68 Z is one of those two), I wish all of them had the BC's as well.

Keep on looking -

Thanks Bill for some excellent information.
I'd like to share what we found in our Nova where many build sheets were commonly found. Our son's L34 Nova was restored and what was found was actually two build sheets. We believe by the last digit of the build it might have been two cars prior and had very few options but there we had it, our Nova build sheet along with another cars. They were tucked in the bottom of the back seat and the top one is son's car and the bottom car is a red with black std. bench. Note the sequence # 226 vs ??4, hence the thinking it might have been two cars before.

Restoration / Trying to figure what steering boxes I have ???
« Last post by DAVEN1256 on February 22, 2017, 01:11:45 AM »
I have a '68 with power steering. I've been trying to make up my mind whether to have a 12.7:1 fast ratio conversion by Powersteering.com done to my original power steering box.....or to go with the Cardone IROC box (pn 276550), also with a 12.7:1 ratio. The Cardone 276550 box is the one I always see mentioned as "the one to get" for much better steereing.

Ideally, would have prefer to keep my original box with new innards but that is a whole lot more expensive than doing the Cardone conversion when buying the Cardone box at a local parts store ( no shipping something very heavy each way).

Not having made up my mind, I bought a Cardone box from Advance Auto Parts just to compare to my original box. I was curious as to the ratio of my original box and wanted to be sure the Cardone box was actually the 12.7:1 ratio.

http://shop.advanceautoparts.com/p/cardone-power-steering-gear-domestic-27-6550/3791467-P

Doing some checking using a homemade degree wheel and a protractor, these are the results I got. They may not be dead nuts but they are close.
----------------------------------------------------------------------

My original box: Number of turns lock to lock: 3

One full turn of input shaft = 20.5 degrees of output shaft turn

Input to output shaft ratio: 17.5:1

Total degrees of pitman arm travel lock to lock: 62 degrees
-------------------------------------------------------------------------------------------------

Cardone 276550 box: Number of turns lock to lock: 2 3/4

One full turn of input shaft = 23.5 degrees of output shaft turn

Input to output shaft ratio: 15.1:1

Total degrees of pitman arm travel lock to lock: 65 degrees
--------------------------------------------------------------------------------------------

I see a lot of conflicting information about what an original '68 power steering box's ratio and number of turns lock to lock should be so I don't what I have here. I'm sure it is the original box.......Any ideas if this is a standard power box or possibly a fast ratio?........For what it is worth, I have the long pitman arm (5.8 inches center to center)

I was surprised that the Cardone box's ratio was so far off. Has anyone else bought one of these and found out they were not the 12.7:1 ratio? Maybe I didn't get the right one.

Thanks.....Dave

Wrong impression. It is very rare to find production documentation in a Norwood car. Back in the '80s I probably dismantled a few dozen and never found anything. The Gibb ZL1 BCs exist because they were left inside the car and he saved them. Apparently that was common but most dealers discarded them during prep.

I had a 1970 Chevelle fairly new; there were BCs in the seat springs and stuck inside the front fenders. I suspect that is where these rumors come from but they do not apply to Norwood Camaros.

That's good information. I didn't know there was a difference between the two plants. Thanks again for you help.
