1995 F150 4.9 clutch 10" vs 11"

I ordered parts from Rock Auto before I had the transmission off. I ordered a 10" clutch from them. I installed the pilot bushing from that kit. When I went to install the clutch I noticed to bolts were to large to fit through the new pressure plate holes. Dug my old clutch out of the trash and noticed it was actually larger...

Should I risk the return to RockAuto or just keep the clutch I bought? Only issues is I have no idea what size bolts I need in order for it to fit on the flywheel.

From what I have read on these forums, the flywheel is drilled to use either a 10 or 11 inch clutch. Is there another set of holes a little farther in that are smaller diameter? I'm thinking probably 5/16" diameter is what the 10 inch clutch would take and the same length as the bolts holding your other pressure plate on.

I just used a 10 inch clutch in my '88 F-150 and it serves me well. I never paid any attention to the extra holes in the flywheel.

The 11" uses 3/8" bolts. The 10" uses 5/16" 18 thread bolts. Yes the flywheel can use either. I ended up just going to Home Depot a bit ago and bought some bolts so I can use my 10" clutch and not have to deal with the hassle of shipping my other one back to rock auto.

Is this what you fingers typed but your keyboard posted?

11" = 3/8"

10" = 5/16"

Fwiw, rock auto is in the business of shipping parts and are generally very good with returns.
