I am installing a NV4500 with advance adaptor bell housing that was said to come out of a 3/4 ton chevy 4x4 truck into my 78 GMC 3/4 ton truck. The shaft size is a little less than 1 1/8" and the pilot shaft is .59, and it is 10 spline. This should indicate that it really came out of a chevy. My problem is I have tried a couple of different chevy clutch sets. Both almost fit but will not slide on the input shaft. I filed the input shaft of any burs or nicks that may prevent them from sliding on.
The clutch may go in about 1/8" . I can take the clutch pressure plate and it will slide on my sm465 transmission. The input shaft of the sm465 is 1/16" less than the stated 1 1/8'. My NV4500 input shaft is almost 1 1/8". The pilot tool is 1/16" less than 1 1/8".
thanks in advance.
