I have an '84 Jetta; replaced the clutch last summer. Had a friend do it. Seemed to do a good job.
Well, the unit is slipping a year later. I also found out recently the previous owner changed the transmission from the original to a Mk2 manual trans.
I had my friend install an Mk1 clutch. Could this clutch have been undersized for the transmission?
The new clutch barely has 1,200 miles and I drive it like an old lady. The timing was off and I had to feather it into 1st gear for months due to the lack of power, but I doubt this would have worn it significantly....
