Reckon half an hour with a lump hammer, new o/s/r light unit, take it to Powerflow to sort the exhaust. Might need a bit of a pull on the o/s/r quarter, but I'm sure you have a few big trees and a bit of chain laying about.
Weld down the rear hatch, added body stiffness and you are there.
Sorted track car, look on the Ring as a shake down session!!!!
