47-55.1 1953 project truck flywheel/clutch match?

[Bigdawg64]

Hello all,
I purchased a 53 Chevy pickup. Completely disassembled. When I got ready to install the tranny, I noticed that the clutch assembly was to small. I ordered 4 different clutch kits and none of them fit. The flywheel has the bb on the engine side top line up top dead center. Motor is a 216 inline 6. Machined surface for the clutch measures 11”. The diameter of the flywheel is 13” ish. I feel like flywheel is correct for motor but after 4 failed attempts at ordering clutch, I might just try and order the whole assembly. Any thoughts or help would be extremely helpful
