Thanks Pete. Have a question for you then. Did it interfere with the front seat any (as far as clearance with the brackets), probaly not, but thought I would ask. What about foot placement in the rear floorpan? Cumbersome? Or is the protrusion minimal? Thanks again Pete.

talk about getting in on this post late, but should the engine be in the car to do the connectors. Mine is still on the stand waiting to go to the machine shop. Any disadvantages to doing the cage, SFC without the weight in the nose?
In a word no. The only time you really need to have the car at wt. is to set ride ht.
If you are using a motor or mid plate bolt those in. It will create some stiffness.
Also unless rules say so go through the floor. It is by far the strongest. But any connector will work, some just better than others.
Tube cars are not as stiff as peopel think is correct but they are stiffer in the places that it needs it. They special built. Look at some pics of fast cars at top end. You will see most have the left front tire either just off the ground or just touching.
As for the front not touching on the jacks. That means the car is already a little bent. depending on where the bend is the frame connectors and cage will straighten out the car. But it should be level or close to it. Re check to make sure the jacks are level. The floor might not be level in the area you are in. Set the jacks where the car will sit and level them front to back and side to side. The mark the spot for the jacks. I will bet that the jacks are not level/even.

Just for reference, I used 2 x 3 x 0.125 tube with the 3" being verticle on the boy's 72 duster. I went all the way back to my MP inboard spring kit box by only cutting out the TOP 2" where it interferes with the rear subframe ( Like ken is asking), so I overboxed the original subframe. What is strange to me is, with the above done the floorpan DID NOT need to be cut open, as it perfectly butted against the floor when it bottomed against the original frame rails. I am wondering if my framerails are taller than some others that have done A bodies?
Anyway, my framerail has not been put to the test, but it was nice to not have to cut sheetmetal. This also allowed welding the rail to the floorpan (where the ribs allowed contact to be seen) all the way foreward to the higher section for the front seat. I think that my car was built different than many others, especially since I used bigblockdart for reference, and If I recall they had to cut the pans! Maybe I got metric tubing-LOL
Hope this helps

There are probably 100 hack jobs for every tasteful, well-built car. We need more people to go "too far". Nice work!

Man Pete, after reading your post again, and how you said you did not cut it, I went and looked at your pic. I thought you HAD cut the floor, and the connector was running THROUGH the floor (I did my Mustang that way, which is why I assumed you did too). Wow! I did not realize it was just FOLLOWING the bottom of the pan, even more impressive then I originally thought!!!

Read the post and I had a thought that I haven't heard anyone mention. I've attached a pic that vaguely illustrates the welding technique I am considering. Not sure if it's a good idea, but it seems to eliminate what would appear to be a byproduct of welding around a single cross section of a subsection (frame-rail). The idea is to cut the new section at angles that will be welded along the 'rails' in such a way that no two welds are adjacent to each other, therefore the old metal does not have a single cross-section weld that creates an 'overheat' weak-spot.
Any questions?

Hey OldTimer...
Do yourself a favor... If you are cleaning the undercoating off of the entire underside of the car, go out and get a cake serving spatula. There exists a 10-12" long, flexible flat steel with rounded tip. Makes removing undercoating from the trans tunnel and all the radiuses SOOOOO eaasy!
I think I posted a pic of this once before. I will see if I can find it. I have tried EVERYTHING and this was the best by FAR!

Heck, I would even be willing to send it to you, as long as you sent it back after you were done!

The technique I used for the rear part was as follows:
Cut a 2x3" opening in the rear frame section. Slide in the subframe connector (easier than it sounds), and do a 360 degree weld at the opening (lap weld). Also want to have 4 or 6 holes in the rear subframe where the connector is stuffed and do some welds there too. Cant make the rear any stronger than that. As for the fron, it's just a typical butt weld. Couple gussets can't hurt.
See enclosed pic of rear on my 71 RR:
