I am looking to chop the crap parts off the rear of my frame and extend it a little. The way I want to go about this is to find some square tube to fit directly inside the frame so I can have them overlap by a foot. I was wondering if any one knew the right size tubing to buy to make this happen. If any one could recall specific threads that its been done that would be great. Thanks guys.

 

loose your tape measure again??

I take it the vehicle your doing this to is your 91??

Do you plan on having some angle bent to the correct size then welding it to make your insert.

Or just go with off the shelf square tube that might come close .

If I had a 91 here I would be glad to measure

 

I boxed it all in at one point and undoing my goof ups so I cant get a ID measurement, only OD, just got some 2x3 and it seems close enough.
