D2 pony big end bearings

I am in need of some .40” undersized big end bearings for a D2 pony engine

I can only get .30” from Cat, any ideas if I could source some?

Failing that a spare crank

Thanks

I believe that some of the BMC "A" series BE bearings will fit. (BMC as in Morris / Austin mini minor, Cooper S).

Would anyone have a good crank for the pony engine that they would sell?

Thanks

I have this one. I think it's standard but I haven't measured it for a while. I can measure it if you're interested.
