I have a 93 coupe, originally a 4 cyl auto. Now I have a 5.0 in and t5. I bought the oem replacement clutch cable for a 5.0 and the rubber bushing that goes into the firewall is way too big. Am I supposed to run the 2.3 clutch cable kit instead? Hole in the firewall is a quarter inch+ smaller than the bushing, no fudging it in either.
