I found this yesterday still attached to the underside of the pass bucket seat. The car presently has a 1979 truck 305 engine. As there are no codes for any of the optional engines is it safe to assume that this car had the base 283 engine or is there something on this tag that says that. Thanks Percy
I put your note together with your pictures, flipped the pictures right side up and also you will see I whited out two 4 digit codes which are your key codes for the ignition and trunk locks. Best not to have them in the picture!
You may have told me already but I see it has F40, HD suspension. Does the car have a 12 bolt diff? I'm betting it does even though it was built with a 283 (as Cam mentioned, no engine option listed so it was a 283) and an M35 Powerglide. I don't think I've seen a full size 66 Canadian Pontiac yet that was built with F40 without having a 12 bolt.

Dad owned a 1966 Oshawa-built Biscayne from Dec '65 - Jan '70. Sandalwood Tan with Fawn interior, it had maybe 2 options, F40 & T60. It had a 250 & 3-speed manual. I sure would love to go back & see if it had a 12-bolt, but going back 54+ years is something impossible.

Crazy as it sounds, I bet it was a 10 bolt. For some reason it seems that the Chevs with anything below a 327 got a 10 bolt even with F40 and the Pontiacs got a 12 bolt as soon as they had F40, even with the 6 cylinder. Not 100%, it seems there are exceptions but for some reason the general findings are that way.

Thanks Carl and you are right the car has a 12 bolt open 3.31 rear ,13/16 front sway bar. I was going to get the G.M. documents but now that i found that tag and the protecto-plate was in the glove box ,same name as the ownerships are in now i dont think there would be any information that i dont already know,thanks to this site!
Carl, I believe you. Usage varied from year to year and line to line. Chevy coupe and sedans with the standard V8 that year were running 3.08s on the 1500-series (Biscayne / Bel Air) and 3.36s with 1600 (Impala / Caprice). I would expect that the Canadian Pontiac 7500-series (Strato Chief / Laurentian) ran 3.07~8 & the 7600 (Parisienne / Grand Parisienne) ran 3.31~6. Pontiacs were a step up over Chevrolet in the GM hierarchy and maybe it, and likewise the upcoming decision to make 6" wide wheels standard over Chevy's 5" were born from the same divisional status. Tip of the hat to the Wide Track.

That 12 bolt makes sense.
Determining what used the 15/16" bar (other than F41 cars all did) seems to be a crapshoot. Lots of guys say F40 wagons used them but I've seen SO many wagons that should have a big bar then that don't, it can't be that. I've certainly seen way more small bar wagons than big bar.
Yes, if you have a protecto plate and the build tag you pretty much have it all.
