sm420 clutch question

[Cothran]

Does anyone know if an 11" clutch disc from a '67-'72 chevy truck will fit the sm420? Part number is 90-008. I've searched a lot but haven't been able to find a part number on the forums. I've also seen a lot of talk about getting a 10 15/16ths disc, etc, but haven't seen any part numbers for that either. I just want to make sure that this one will fit, then I can turn it down if I have to.

I run chevy 11" clutch disc with toyota pressure plate and throwout. While it is about the 1/16th too large too large you mention, it will "self clearnace" upon startup. Sounds kinda like a sppon in the garbage dsiposal for about 15 seconds, and then you're cool. Or you can grind down the pressure plate side on a bench grinder, but why bother...

I bought mine at http://www.dialaclutch.com/

It is an 11" but if you run a tape on it.....10 and 13/16th. Part # they used is LD3348.

Great, thanks guys. I'm going to need a chevy pilot bearing too right? Otherwise everything else stays stock - 3 spd flywheel, throwout bearing and pressure plate?
