Hi, I am looking for a swb frame to buy.

I am unfamiliar of the differences bewteen them , but I will have a 56 frame ready soon. Of course, it is a leaf-sprung rear, but I believe the 60-66 are coil sprung, are they not? In any case, if any interest, just throw me a pm.

I just found this add maybe it will help.

I don't normally access the 60-66 parts board, but I have a nice 66 SWB frame that has been sandblasted, but not painted. It has been stored inside, so it has very minimal surface rust only, and is in nice shape. Complete roller, 6 lug wheels, front bumper brackets,and good dealer installed type heavy rear bumper.
I got it on a package trade deal with some 72 parts, and was told it was for a 68-72 model. However, the frame VIN indicates it is a 66, and my 72 short bed holes do not line up correctly. Sorry, no title for the frame.
I don't have a digital camera, so no pics.
I live about an hour due East of Dallas.
Let me know if you're interested. Asking $250.00 for it. Thanks.
