Now that I'm older and wiser... Well I'm older anyway. I used a C Clamp to bend, dimple, flatten the tubes as necessary. Works pretty good, you can stick a nut or a piece of metal between the clamp and tube to get the desired bend.
"EDIT"
It helps to put something (block of wood, piece of metal) on the side of the tube that you don't want bent, flattened, dimpled, etc... :salut:
