Reply to thread 'Procedure for replacing flex joint?'
from Needswings U will get the correct parts ,,,

example e bay and parts store,, most aftermarket flex disk the steel inserts are too big,, yes you can make them work(install) when pull them in with a wrench but U may not get them apart later with out a pry bar and a hammer ,,,the ones you get from needswings are not interference fit they are the correct ones.. when u remove the driveshaft look at where the slips joins come apart, one half of the driveshaft has 2 bumps and the other 1/2 has one bump this is the balance alignment ,( it is like take your left hand ,hold out 2 fingers and take your right hand and put your one finger between the two this is when you reassemble the driveshaft. jim
i though i posted this but 3 of my post have come back undelivered.. it is ease if u remove the muffler,, My first v8 ran 655 runs down the 1/4 mile and both flex disk were never replaced ( i did not use aftermarket ones,,, got mine from needswings. )
