Looks like the short Bellhousing, as I suspected. Panthers typically use the long driveline assembly with a short bellhousing to get their depth/ DL engagement correct, where Berkeley uses a long bellhousing w/long DL or short w/short. If you were going to use that bellhousing you would need the 6 3/4" drive line, the one that has the crank flang built on to it.
Now that I think about it, it seems like alot of horspower to put into 3 point mounts anyhow....
