Go to an Industrial metal supply house and ask if they carry 'Rems'
They are usually not perfect. But you might find just enough length out of a damaged 12 footer, or multiple ones.They usually sell it by weight.
Thats what i did when i did my connectors on my Pinto. I picked up 12 feet of 1 1/2x3 .125 thick and had it cut for about $25 and all the rest of the steel i bought was around $12 to $15. For $40 I picked up a heck of a lot of steel.
Dont even think of "Home Depot" THey have a limited supply and its Sky HIGH.
Hope that helps you some.
