I have an oportunity to purchase the shell of a Thunderburp SC, basically they gutted the engine, transmission, and interior. The reason I am looking into buying it is because ever since I replaced the front air bags in my Mark, the tail just slowly dropped over the next weeks until it sat on the snubbers where it remains until the end of road salt season. But that will not happen if I cannot either trick the car into raising the rear, or install real springs in it. I was hoping to use the rear lower control arms and springs from the SC, and as an added bonus, get a PROPER wheel bolt pattern ! Unfortunately the car needs to be gone in a couple of days, does anyone know if the springs sit in a removable spring pocket or is it integral to the control arm ? Are the control arms even interchangeable ? What about the differential ? One of the arms on the SC is broken, so I will have to buy another control arm if the spring pocket is not removable.
