pilot bushing??

the larger bushing/bearing (pilot bearing they call them) that fits in the larger torque convertor pilot will not fit in a 1965 crank. the cranks were changed as far as the dimensions go in/for 1968. The other bushing (original style) should work. yuou need to measure the diam of your input spline on your trans (Ill assume its an 833 4 spd) there should be no step and the original bushing only needs to go about 2 inches on the shaft (but it varies, could be less) compare the old and new bushings, you may have gotten the wrong one bu mistake. The size of the input shaft did not change as far as I know from when they were first introduced. ( in 1964 I believe). the bushing should be the same. There shouild be no step. this step you have may be wear from the original bushing.
