1967 YR1 Crankshaft Rebuild Parts

Hello,

New member here.

In the middle of a 1967 YR1 engine rebuild.

I have pressed the crankshaft apart and I am now on the hunt for replacement parts....

Does anyone know of any reasonable sources for parts? Hoping to cross reference the Koyo bearings if possible.

I know the con-rod journals are shot, and probably the connecting rods....

Any suggestions welcome.

Thanks,

Redbug2
