My K15 cross member mounts only have one set of holes but the measurements match up to the set the old mounts were using on the C30, I assume the other set were for BBC motors. If I used the original motor mounts that were in the C30 the motor mounts almost perfectly but if I use the new ones I picked up for this install passenger side matches but the driver side is 2 inches from fitting.
