Tube for sliding inside frame ends ?

[roundhouse]

Anyone know what size square tube I need for sliding inside the end of a frame ?

Mine frame horns are bent a little from an accident years ago and I’d like to streighten them while I have the rig apart .

Wall thickness depends on what you want. Or what you find.

My '77 frame measures about 2-1/8 X 4 inside the frame horns. I can slide a piece of 2x4x3/16 rectangular tube into it, and it's a little loose side to side, but tight top to bottom to the point that it takes a little tap-tap-tapperoo to get it in and then some wiggle to get it out.
