Not likely, only the 85 Celica GT-S had the bigger 7.5" differential, check the vin on your firewall and it will probably have the T-code, if it was to have the F-code meaning 7.5" which is the same as the 82-86.0 Celica Supra's had, it would. Not all 85 GT-S's had the F code, so be sure to check your vin for the Diff code.

Yes it will. The 1984 yz490 and the 1985 yz490 are identical bikes other than the front disc brakes.
most jimmy 4x4's don't have a posi rearend unless it was special ordered and you will have to measure your pontiacs rearend from hub to hub and get the length and then measure a jimmy's to see if it's the same or real close.
No, they will not interchange.
yes it will. any camaro door 82-92 should fit
