This from the Pontiac Brochure. WHEELBASE-119". Front and rear tread, 60.3" and 59.3". Overall: length 212.22", width 80.7", height- Sport sedan and sport coupe 54.0", sedans and convertable 56.0", Safaris 56.3".
As soon as its warm enough I'm going to chuck a 4 door body away and compare the frame with mine to see if theres any difference.

I would say yes and no! Yes the frames would be the same, however the four door models may have 2 or 4 more body mounts(I'd say 2)! The bodies would sit on the chassis perfectly except you may have a couple of extra frame to body mounts not in use if you mounted a 2 door on a 4 door frame. Think about it for a minute, would GM rather build 50 million frames(exageration) all the same/similar or build a different frame for every body style, the re-tooling would have bankrupted them alot sooner if they did. I built a 57 Chev 150 two door sedan on a 57 Chev 210 four door frame. I would say GM probably had 3 frames in 1960 that were very similar but not the same. (One) would be a convertable frame(no metal roof, stronger frame)................(The second) would be for the 2 and 4 door Sedans and Hardtops........And the third would be for the station wagon.......buuuutttt I may be wrong on the station wagon. I'm thinking the wagon is longer and maybe a different section of frame behind the differential. Gas tank mounting, spare tire area etc! As we say in Alberta..........Just Giver!!!
Ed M: your '60 Pontiac looks sweet. Anywhere I can find bigger pics?
If you're refering to the little picture of the gold coloured one it is just a pic I found online. Mines not that nice yet, you can check the registry for a pic of mine.
