[63gmc4x4]

Finally found a clutch from a store that will work, the disc is exactly the same as my old one , go to O'Reily's and order part #K7037501hd, they had to get it from there warehouse but no big deal! I found it by thinking back when I did my T5 swap it came with a 11 inch clutch 14 spline for the T5 from a Astro van that worked perfectly for the GMC flywheel and thought wonder if they made it in a 10 spline, so looked up Rock Auto and seen they listed one that said 11 inch 10 spline, then looked up 1991 Chevy with a 4.3l to see if it applied like the astro van clutch and see if there where more options on Rock Auto found one that said with steel back so used that part number and Googled it ,came up on O'Reily's so looked at there pics and little video on there site and seen the disc is flat just like GMC ,so I ordered it took a couple of hours to get it but , now I have warranty on one and can get it locally of needed at anytime, it's going in 634x4 with the 401M!
