I thought you had found a 3/8 stroker? Now you need another one?
All I've got is a couple stock cranks of unknown origin. One came out of the last Donovan I bought, and the other came with the first one. I have know idea what they are other than they appear to be std/std. I suppose if a guy wanted to weld up a stroker they might be good cores.
I'll keep a lookout.
