Finally tore into U13, dropped trans/transfer case, pulled bell and clutch literally fell out. Disc looks the original 9”, flywheel had chipped teeth. Hoping for quick fix I drove to local Ford place, and was told parts computers only go back to 1980. So crossed street to NAPA, and gave them old NAPA parts # for LUK clutch kit. Kid said not shown on computer, but he did call their distributor who advised not available. So got kit over night from OReilly, which I’m sure is Chinese crap. Maybe I’ll luck into a Vietnam Made kit. I have been enjoying the U13 and have not started “restoration”, so not to upset about putting in this kit. I’m anxious to get off lift so can start on off road build I just got back from paint. Thanks for help and suggestions.
