For sale; 4 new old stock input shafts for 60s up Chevy or GMC trucks. 2 are 1 and an eighth ten spline and the other 2 are 1 and a half ten spline. I think they are for the Muncie 420. One of the smaller ones has a different number and might be for a 465 Muncie. The #s for the small shafts are 3761928 left and 3787253 right. The group # for both is 4.351. Both of the larger shafts appear to be the same. The number is gone on the left box and #3787254 is on the right box. Note all have 17 teeth on the drive gear and 24 clutch teeth. The clutch teeth are deeper on the left unit #3761928. $125.00 each or $450.00 for all four. Would consider trade for 65 to 67 GTO parts. Calls only. 5one5-5seven0-518four.
