Hi Bill,
Look for the 518's in trucks or vans, real easy to spot, the pan shape
is
the same as a 727 but deeper so you get a good pan from the start. Our
65
Coronets do have a larger trans tunnel than the early A-body but the
rear of
the trans where the OD sits might need some floor massaging. maybe those
GM
transmissions that Keisler sells are more compact, I really don't know.
It
killed me to make the opening in the floor for the Jerico.
Joey
