I have an axle code in box 29 that says "OK-1" . the car is a '70 gs455 w/ AC so I expected a 3.42 code. Does anybody know what "OK-1" means? Off subject, I can't imagine the wheelspin with this car when it was new. 455 (one legger maybe even) and G-78 14 tires. ou:
Adam, I've been through 3 different books, and can't seem to find that code. Are you sure about the OK-1? I know sometimes they can get hard to read on those old sheets. It also just may not be in any of my books or I keep over looking it. Some of the codes I'm finding for rear ends are order codes like G1 & G4, their UPC codes are G91 & G80 Someone on here shurly has access to other code books. We should be able to get an answer for you. Jeff
Amandas '70 GS 455 w/AC came with a 2.94? open rear, I think that was common for non stage cars. I'll dig out the build sheet and see what code it has.
OK Axle Code I have seen 2 buildsheets, both from Framingham Mass, that had the "OK" code for the rear axle. One was from a rusted-out 70 GS 455 we used to help create the X-Camino. That axle was a 323-posi and is under the X-Camino now. That rear axle ratio doesn't even show for a GS, but who knows if it was original or not. I never looked at the date codes, and was under the gun to get the car finished. The same sheet lists an "SS" for the radiator. The car had air, so I am figuring it had a large 3-core rad. Other plants would have listed it as "SJ" or maybe "SW". The other car was a 70 ? (Skylark or GS 350) and it had a 2-series open rear. I know they built vehicles other then buicks at the Framingham assembly plant. Maybe they were not used to axle codes other then "Chevys" and didn't know what to call them, who knows. I have seen many weird things done on 70 and 72 Framingham cars. I don't think they followed everything the other plants did when building them or creating their build sheets. When you ask questions about build sheets it would help if you include the assembly plant along with the year/engine/type car. There are many differences between plants and this will narrow down the variables. Hope this helps. Duane
Duane, You mention that the 3.23 axle ratio doesn't show for a G.S. Actually, that is the standard ratio for the '70 GS350. This is on all the charts in the parts catalogs, assembly manuals, etc. If you'd like more info, let me know and I can provide some copies from my manuals.:TU:
Sorry for the lack of response, Ive finally been in-transit to Chile and have minimal access to the net right now. The car was built in the FREMONT, ca PLANT. Other than that, nothing unusual about it besides the Rivera color of Azure Blue as an option. What a sharp color for that car!
Darren, I was talking about a 323 Posi not being listed for a 455 GS, and inferring it might not have been original to the car we scrapped. You are correct they are listed for GS 350's. Thanks for keeping me on straight and narrow. Duane
aha, that makes sense. The guy that had the car a few owners ago said the car had tall gears and he switched the rear out. Thanks so much for the help everyone. This baby-blue cruiser must have belong to some lucky wife or travlling salesman :Brow: .
Y41???? What's Y41????? It's on the Body Production Sheet, Brenda and I pulled out of my GSX yesterday, only took 7 years too think about looking for it! It's got Y41 written in magic marker on it with what looks like some one initials. Also any thoughts on how to flatten it out?? Thanks RV
Roerta: Could you describe where your sheet was located and what if anything you had to remove to see it? Jim Lore
Jim, took the drivers side a-pillar molding off. In between the A-pillar and the dash, we saw it fold up and stuffed in the a-pillar. I shined the light up from underneath and Brenda saw how it was stuck in the pillar so she said "let me do it", and she was able to get her hand up inside the dash and pull it out. My car was undercoated and that didn't help. I orginally thought we might get it out from the top, but that would not work. Hope that helps. Roberta
Y41 Y41 was indead the sales code for the GSX in 1970. As for flattening it out. I am not sure how brittle it is but you may dry a light misting of water from a mister and then try to iron it on low heat. The only other thing I can think of is carfully straighten it out and lay it under books for a while on a flat surface. I can do a repro of it if you can find a way to send me a copy or if you can take a photo of it with a digital camera. Mark Macoubrie
Duane, it's in the works, but it's mighty wavy and crusty, and undercoated. Also got a call today from Wayne R, he's got the stuff ready to send me, I have to call him back, BTW, it's #14, the body sheet says 2--5-70 and the cowl tag is 02D, so the body must have sat around for a couple of weeks. More soon, we probably need to yak in person! RV
Roberta, They built the GSX's in batches, especially the yellow ones, due to their special paint color. You can see this trend when you've collected enough "build sheets". I have sheets for 3 yellow ones that were built on the same day. More likely your "paper work" probably hung around until they had enough orders for a batch. Glad to talk whenever you want, I still owe you for all the help you have given in the past. PS. Have a happy holiday. Duane
