The door to fender gap is likely in the .25 inch range on that "1970" car.  From my recollection, production fender gaps could vary significantly from car to car.   And I've had ten 67 to 69's when they were original.  They built production cars.  Not show cars.  How many restoration shops today custom work the fender and door leading edge by welding on or removing material to get to 1/8 inch gaps?   I'd bet most of the top show cars are massaged in  that manner.

 Casting date late March 69 and final assembly Jan 20, 1970.  That is a long time, but would indicate that Gear & Axle used whatever components were on hand to complete an axle assembly.  Probably not "normative" but the plants didn't operate on that principle.

That is one killer induction setup.  Never seen one like that for a clickety six.

Does that spoiler look a bit taller than the production intent part?

I can verify that there was an actual ZL1-based 454 test/development engine stored by Chevrolet Engineering for decades at Milford Proving Ground.  When I first viewed it, the engine was in a disassembled state and was kept in a custom wheeled, varnished wood crate.  There were retaining spaces for all components down to the individual valves, lifters, pistons, etc.  The crank was held by a cradle integral to the interior of the crate.  The crate exterior had information indicating that the engine had been shipped to Diamond Engineering out of the Detroit area at one point.  The block and heads were aluminum with corresponding Winters Foundry casting marks.  This engine was secreted away along with several other high performance small blocks and an L72 big block in an area away from prying eyes.  The fellow who oversaw the storage area showed me these engines early on in my tenure as he knew of my interest in such things with the agreement that I "forgot" what I had seen.  Eventually, an enterprising co-worker who also knew of the engine(by being buddies with the storage guru), decided it would make an interesting development study by installing it in a C1500 pickup.  He got permission from the storage guru to temporarily use it and the install occurred on a weekend during off shifts.  I had an opportunity to drive this combination on the road system including the North/South straight with my co-worker riding shotgun.  It was an animal.  I can only imagine what it would have been like in a lighter platform.  There is a possibility that this was the same engine described in the account of the Corvette mentioned previously.

Thanks for all the feedback. 
Re: the reproductions...if you have to create tooling anyway, why not get it a bit closer to production intent vs the current attempts?  I guess at this point suppliers are more concerned with being functionally adequate. 
RE: removal...yes they are tough to remove due to the stiffness of the tabs.  But it can be done with a couple extra minutes and some finesse.   I've done it on other Muncie cars.  My fault for not removing myself prior to sending the car to the body shop. Lesson learned.
Bottom line is it looks like I'll be massaging repro's to better resemble the original clip, installing them and moving on.  Geez, it's these little things that drive me nuts, lol.

Restoration / Muncie Speedo Cable Clips
« on: September 16, 2023, 04:34:47 PM »
Who has the best repro Muncie speedo cable clips? 
Ordered some from Classic and they're not even close.  Had to use a 3/8 steel pin to form the new one and get a comparable curvature to the original.  Heartbeat is on back order for theirs and the photo doesn't provide a good view to compare.  It's a stamped steel clip for cryin out loud.  How hard can it be to COPY an original?
I only have one original left from the firewall as they they "lost" the ones in the tunnel.  The gorillas at the body shop trashed the tabs when they removed it. Hardened steel only has a couple iterations of bending and it fractures.  So I can't even use my remaining clip where it originally was installed.
As always, any info is appreciated.

RE: Glass thickness ... I heard that some are relatively thin vs production.  I suppose the difference is compensated for by using a thicker seal for installation.  I'm sure CRG members with information in that regard will chime in.

Looks like I have an answer. 
It appears that some of the suppliers either:
 a). have the wrong dimensions entered in the coupe listings
or
 b). their glass is not correct. 
I contacted local supplier Heartbeat City and they confirmed all their coupe windshield glass is approximately 20.25 inches in height.  That is within 1/8 inch of my old windshield glass and will fit without any issues. 
So I'll head down there to pick up my new windshield while saving the shipping cost.

Restoration / Original Coupe Windshield Glass Dimensions
« on: August 23, 2023, 10:09:37 PM »
I have been looking online at all the new windshields that are offered.  What caught my attention were the dimensions listed for all of the replacements.  In particular the vertical dimension of the glass.  My original is 20 1/8 inches in height but the new ones are listed as 22 inches.  I ran the tape on my windshield opening and 22 inches of glass will put the bottom right at the point where my lower windshield trim clip screws are located.  That's a no go for lower trim installation.  Something is definitely not kosher here.  The original will drop right in.  Does anyone have any info on this difference?  I conducted a search on this subject but nothing turned up.  Scratching my head on this one.

So mid July of '69 was when the running change for the "C" prefix was rolled out.  Good information.

HawkX66 - Great shots of the bracket and the hex head screw that retains it to the A pillar.
BTW...It looks like my brackets got tweaked when the body guy removed them.  Your pics will help to get them back to the correct orientation.  Thanks again!

With the "C" prefix could that be a 1970 Nova axle?
