Although they won't interchange, the only external dimensions that differ between the Milodon 318/340 & 360 pans (to my knowledge) are the end seals. There is no interference on my car using factory motor mounts. Milodon calls the standard pan a low profile but really it's not, it's a big 8 quart deep sump. They have another called a low pro which is a true low profile, it has cutout for the steering link. Can't recall why I didn't use that one but must have had a good reason.
