Rear disc brake gear ratio
I am looking at a 79 and 80 TA for parts and both have rear disc brakes.
I just want the posi unit to put in a non rear disc brake rear end.
Were the rear disc brake gear ratios the same or could you get any gear ratio?
The 79 had a 403 Olds, the 80 had a regular 301 engine.
Thanks
