I have both springs and Arms here,I am flat out at the moment to pull them off a front axle but if you want a couple of arms and some springs call in during the week, bring a 19 mm spanner to get them off and they are yours..
German wrecking has gone to pack since Tony sold out.
It would be dead easy to use a pair of coil overs instead of the springs and the shocks . it would mean making something to attach the top up inside the crossmember where the stock spring goes and a mount on the lower arm. it would shave a ton of weight off the car too.
