Hey usmcdad,

I'll give you a bit of info:

good & economical welding are not often used in the same sentence.

I'd check the local race car chassis fab shops in the area. I'd not cheap out on any cage work you or your son plan on getting installed.

You probably don't need a C/M cage. But a nice mild steel cage that conforms to NHRA specs will do. Google search the specs. Remember: It's better to have & not need then to need & not have.

Good luck.
