REAR END SIZE?
 

Any one know what the size of the rear was on 79-85 GTs. Was it the 7.7"? I know 86 was the first year fir the 8.8 inch, but I'm looking for a rolling chassis without rust as early as 79 (for no emissions and classic car insurance). Also any one know how much has to be changed to make a 79 look like an 87-90-is it just the bumper, headlight panel, and hood that has to be changed?Thanks for any input

You can't wait a year for your 86 to be a classic?

The rear ends before the 8.8 were the 7.5".

Most insurance places around heer are 25 years for a classic car-and my frame is bent and i have no floors (rust sucks)

so how do those number work?

It's the rear differential. The 7.5 or 8.8 is the diameter of the ring gear. Bigger gear can take more load.
