Jaydee, one kit that hasn't been mentioned is Kenmer, here in Melbourne. Martin Govert (owner) is helping finish my Harrison. He's a highly experienced fabricator and he works closely with the engineers so you get the right advice (whether or not you take it!) and the best chance of getting through engineering. He has one of the better looking Cobra bodies and the kit is delivered with all brackets and mounts are in place, ready for everything to bolt up.
Kenmer Engineering
The website is a bit out of date, as he now offers custom suspension with plenty of wheel/diff/brake options. He can can fit everything from LS to Coyote engines, power steering, ABS brakes, etc. If you're still considering a local kit, I'd definitely be checking out the Kenmer offering.
Best of luck!
