We will talk next month. Changing springs is not to bad. I changed the springs on my 500SL with Eibachs. These seem to be just right with the HD Bilstens. The front is faster than the rear to change. Total about 3 1/2 hours. You will need to keep the compressor long enough to change the pads if the car is not level. Don't worry I need the tool back here in my shop. We can run the deposit on your card this is ok with me. My shop is KKM Precision we are a CNC machine shop. This is were the card will run through. Kevin
