tubular rear end

alrite guys i got a 96 avenger and right now its on cylinders. The back didnt sit low enough so i cut the inside lip of the fenders out so id have room for the tires to tuck up in and then i cut 2 inches out of the bottom mounts. When i had the cans out i let the car hdown and it sat awesome. Welded the mounts back together, put em in and now i wont go down all the way. Put the ass end back on jack stands and jacked the tire up. Now the tires are hittin the cans. So now im thinkin about doin a tubular rearend like i saw on a couple cars on here. Only trouble is ive never seen it done to an avenger. So im thinkin bout givin it a try but i was wonderin to anyone thats ever done this do u guys think it can be done to a venge? And if i do this i know the front is gonna sit to high. Actually i still have 2 inches of rod left on the cans up font but the tires hit the frame in the front. So i was thinkin bout c notchin it like all the trucks do. WHat do u guys think?
