When you come up with a big bolt pattern 8 3/4 that drops right in there, I'll pull the Ford out.
Nothing in my car is "chopped" hacked, cut or anything else. The Ford rear is a bolt in, and if and when something better comes along, it can come out.
MOST people look at my car and don't know the difference. So far I've had two guys glance under there and conclude, "oh cool, an 8 3/4"
