Here I made it easy for you. The 12 inch clutch found in the bigger trucks is a direct replacement for the 11 inch found in the smaller trucks and most of the 4000 series trucks. Its a New Generation clutch kit PN# 04-528 This kit us complete with disk, pressure plate, throw out bearing. roller style pilot bearing, and alignment tool. My local vendor actually has a few in stock. so for about 2 bills your good to go. BTW i did the same clutch in my 65 last year, and a chevy 12 inch in my 348 v8 420 trans 60 chevy truck a few years back. BLC
