Tommy; how competent are you with metal-working?
It isn't really a big deal to make things like crossmembers from sheet metal; High school competency will get you a long way and save mega-bucks! If you don't have a welder, new MIG's are fairly cheap nowadays. It might be cheaper to buy one and do a course at TAFE, than to pay someone. I have rebuilt a Series 1 chassis that most people would have thrown on the tip; I wanted to keep the original chassis number
