do 1969 and 1970 fastbacks come with posi or what? sort of stupid question but im learning.

 

i dont know, but if you own the car you can check the number on the door

 

yeah....thats a problem. i currently dont. but im looking for either a 69 or 70 fastback and am wondering if one of the other has posi so i can decide which is a better year to look for....im not real interested in emberassing 1 wheel burnouts....might as well have front wheel drive or a ricer.

 

hell even if they dont just throw one in there, or you could even give it the old lincoln lock for free.

 

oh alright, i didnt know it was simple like that....i thought it required liek a whole new rear differential and axle and just like a whole new rear end whatever......how much does "throwing one in there" run? thanks

 

you might want to try posting this question in the "classic mustang" topic on this site, they might be able to help you with this one, since i dont know to much on the older stangs, if it doesnt come with a limited slip rear end you will need to find out what size rear axle is in it.

 

both came with posi traction as an option..when you find a car just jack up the rear and spin the wheels..simple to find out

 

thanks for the help.

 

didnt they have a 7.5 rear?

 

I want to say 8.5
