The early A body pre-67 has interference on the sides of the bellhousing on the 727 and 518. The floor has to be hammered up at the inner edges of the footwells because it hits on both sides just a few inches back from the block. Probably better to cut it. The 904 and 500 both clear in the bellhousing area on all A's, and the 727 and 518 both clear in that area in the 67-later. I hate doing a search cuz a lot of the info is outdated.
