Clutch kit??
 

I’m working on rebuilding my 1964 1000 305e sm319 and trying to source the parts needed, I’m just wondering if anyone has a source for a clutch kit for these engine trans combo. I understand the rhino pac 04-528 is a possibility but I haven’t been able to source a kit yet, is there anything out there that will work? The disc that came in my truck was a 10.5” set up, I like the idea of going to a 12” as long as it works ,the bolt holes on the flywheel are around 12.25” apart which doesn’t leave a lot of room for pressure plate bolts and the disc. Just wondering if this is normal, any help would be great. Thanks
