engine mount bolts

Looking for the 2 bolts that thread into the biscuits on a big block k frame. Last time I needed a set I got grade 8s from Fastenal but I don't remember which ones as that was years ago. Anyone know a cheap place to get them or length / thread /size? I saw them on classic industries for $30 which seems excessive. Did not see them on 440 source.

I have those, good used correct "38" stamped bolts with the original washers, message me if you still need them
