What other crank fits a F4R

[smokeybone]

Just stripped my spare 172 engine that i have been waiting to rebuild for some time, only to find that i has scored on number three on the mains.
Is there another engine that uses the same crank as the F4R, i remember using a diesel one in my williams years ago, so courious if there something else that will fit this?

Get it re ground and use bearings to suit
