When I did my rebuild last year, they did all my suspension (front and rear) inc. 2 de dion tubes, all the interior panels inc. footwells, headlamp brackets etc. etc. Very pleased with the job.
LADS top tip:- When you've had the job done, put black insulation tape on the front edge of the lower wishbone. You won't even notice it's there, but it will save a lot of stone chips.
