Need to get my truck back up & running so I'm going to install a 7.3 into my '85 with the original T-19 for now and look for a 2wd ZF5 later. Question is which clutch/flywheel set up should I use?
You are going to need a 6.9L solid flywheel and the correct T19 clutch set. The T19 clutch has a pressure plate that mounts with 6 bolts instead of 8 like the 7.3L, so only a 6.9 L flywheel will work. Unfortunately when you convert to the ZF, the SMF conversion clutch kits that mount to the 6.9L flywheel with 6 bolts are obsolete. You will have to go back to a 7.3L flywheel and ZF clutch set when you find a ZF.
