New CV boots with OEM or new aftermarket axel

[JAMAS]

& all 4 boots are the same (even though 2 different part numbers are listed) so if they are out of stock on one, just get enough of the other.

From my experience, the fit is the same, but the spacing between the "bellows" or folds or whatever those things are .....are different.

perhaps it has to do with how each one flexes....not sure, but the folds matched the OEM differences.

....but again to Tom's point....they will all fit inside and outside the same.
