TSM Conversion??

The early 80 Seville caliper has what you want. Is what is used with the TSM conversion on the 8.25, and what i did on my '98. Is plentiful in autoparts stores, BUT are bunches that suffer from bad (cheap) rebuilds. Go through several and try to find ones with new pistons. AZ seems to have the best, lifetime, warranty. Hit the junkyard and find bad ones to turn in for cores thereby saving mucho $$. I like when that happens. Judd
