What size tubing to fit inside the atc70 frame?

[86trizinger]

I have 3 atc 70's in my garage and 1 spare frame that is bent a little.
I want to build a 70 for myself with my parts I have but need to reinforce the frame once I straighten it.

What size tubing do you use to lengthen the frame and strengthen it. I don't want to cut it yet until I know I can get the steel for it locally.

Is that the inside diameter of the stock tubing?

I can check tomorrow, I extended DEEPA's that way. Mine, I got a 3MM thicker walled tubing and replaced the whole upper piece. I'll get some pics :D

EDIT - If you do just put an extension tube in it, drill some 1/2 holes in the stock tube around it and before the ends of the new extension tube. Mig weld those too and it's very strong.........
