How long are the bolts for the ring gear on a 14BFF? I purchased a master kit and the bolts are way too short. They would only enter the ring gear by .140". It seems that the bolts need to be .500" longer. The bolts that came in the kit are 1.725" long. What is the difference in the master kits from 1988 and earlier versus 1988 and newer? My 14BFF is out of an 86 sub. but they sold me a kit for 1988 and newer, maybe this is where the trouble is.
