I am planning to do a frame connector project on my 72 Challenger. The route I was going to go with is the 2x3 tube and cut the floors. My car has done and fully assembled since the 90's. I thought if I cut the floors much of the welding could be done through the top side. Weld the tube completely to the floor from the top, with a few tacks and some seam sealer along the bottom. This would minimize what I had to weld underneath. Obviously there is some welding to the cross member and a bit to the rear frame.

Anyone have pictures or tips of your experiences with this type of connector? While US Car Tool type is nice, I cant see doing this type on my back while the car is sitting on ramps. I am trying to determine just how much I need to cut.

I know this topic has been discussed a lot in the past. I have looked through past posts however, many of the pictures associated with these past posts are now gone.

Thanks in advance!
