The fw to crank can go 2 ways 180* apart. The fw is cast iron, don't use 6013 the weld can be so hard that you cant drill or tap it, this I know, don't try to braze, it would take to much heat. Find another fw! If you are determined to use this fw, use a milling machine with a 4 flute end mill to find original center, then drill & tap. You could tap this hole 3/8" 7/16"or 1/2", thread in a piece of all thread with jb weld, then drill & tap 5/16 fine
