Is the throw out bearing same as original? They make several diff one's.
If there is any slop in rods/holes I would weld them up so you have a tighter fit. I remember having problems with plate under dash that attaches to clutch pedal assembly where the rod attaches also, think it was turning/out of alignment(can't remember exactly).
Were you having any problems before change out?
I just remember this ...the bracket under dash that clutch stops against was bending and clutch went out of adjustment, make sure the bumper is intact also. I ended up welding a support onto the bracket to keep it from bending. Ugly welds...I was in a hurry and bad mood.
