With all the sand rail shops out there.... I'm guessing you have a ton of options!
My buddy built the turbo system on this Camaro and used to build turbo systems for his previous job, full cages, any fabwork for a BMW shop that did turbo e90/92 (v8) kits.

Location: Northridge if you want his contact info PM me. He can do ANY other fabwork you need
TX probably has cheaper labor rates than California....
