273 and 9 1/2" clutch???

I've checked absolutely everywhere for a 9 1/2" performance clutch and as far as I know no one makes one. I checked with my local Clutchmasters shop and he says he can rebuild and hop up anything. That's where I'm going for mine. You can change the flywheel and bellhousing and mess with the linkage and get a 10" clutch in there. If you want. toolman
