Thanks for the replies, Yeah that's what I was trying to figure out for sure if all of the 5r110's are the same case and pattern like I have heard, and if that pattern is the same as say a 4.6 mustang engine..(not putting a torqshift in a mustang, however a 6.0 in a mustang would be interesting.. just need to take measurements of the bellhousing pattern to make an adapter for one and if they are the same pattern I can find an old mod engine transmission alot cheaper to get my measurements)
