hi
i see that you install rear axle 8.8 in your 67 mustang .
i wanted to do it too but i have some thing that i dont know.

i found 8.8 lsd 373 out from 96 explorer .
my mustang is 67 v8 302 and t5 .
if i understand i need to cut the axle in 3 inch and put an other axle shaft like the shorten side.
this is right?
do you have some tips for me ?

thanks
