After 1995, the first gear and front bolt pattern reverted to the Dodge 5.61 first gear and the taller top to bottom 6.043" bolt hole configuration. The 1992 & 1994 GM versions have a lower first gear of 6.34 and can be identified by a smaller front bolt pattern with a top to bottom measurement of 4.685".

By shortening the bearing retainer, this will prevent any interference with the hub on the clutch disc. This can be done by using a cut off wheel or engine lathe. The bearing retainer must be removed from the front of the 5 speed and shortened to a length that is 4.297" long.
