351 clutch ?

I have a 71 FJ-40 that i am swaping a 351W and a NP435 into. The engine is out of a 83 LTD and the trany is out of a F250(not sure what year). The LTD has an automatic trany in it so i will need a new flywheel and a clutch. My question is which flywheel, clutch and throw-out bering do i need. I know that ford used 10 and 11 inch clutches in the 80s and i was curious if the flywheels interchange from 10 to 11 inch clutches.

71 FJ-40 5 inch Alcans, NP435 and 351W coming soon

The flywheels should be drilled for both 10 and 11 inch clutches.
At least the bro's '80 F-150 with 300-6 was, and a friend's '89 F-150 with 351W as well.

Ditto. My '83's original f/w was drilled for both, also. Any parts store should be able to look up those PN's for you.
