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!

You still do the most welding underneath the car to the frame rails, even w/ the style connectors that come up through the floor. Personally I don't like those kind and don't see a need for them to come through the floor. I like the bolt in style from MP that stay underneath the car. Just weld them in instead of bolting them. My cuda has some custom connectors done at the chassis shop that tie in to the torque boxes, spring mount, and the rollcage. All while not coming up through the floor.

for bolt in types you would want to weld them also. I think some 2 x 3 common material welded on the ends would suffice. Tho people have said that the welded up into the floors adds alot of addit'l strength but as you know it would be a heap more work & might not be needed for your app.

I have done the 2" X 3" rectangular tubing on many cars. We used c.m. round tube under my Challenger to tie in with the cage. The cross bar with the tab is my removable driveshaft loop.

I have 2x3 tubing welded to the frame,sanded and painted looks like it was always part of the frame.I also run cal-tracs so there's no twist at all. I tried to post a pix but didn't work? i used the bolt in on my 69GTX then welded them in.works great no twisting and the only place i cut the floor was to weld my roll bar to the connector , but could have bolted it to floor as and option.

Thanks Zippy! that is an awesome thread on the topic. I only wish some of those photos were still attached. The info in the thread is great but the pictures would have answered a lot of questions.
