It depends on what engine it came out with. My Scamp /6 had a small tube 7 1/4 and 9" brakes, so I had to get new shock plates and since the 8 3/4 uses 10" brakes I had to change those. Parts were readily available for brakes at the local Advanced Auto Parts. Everything in stock except SBP drums, which they had the next day for $82.00 each. Everything together (wheel cyls.,shoes,spring kits, adjusters and so on and so on...) $212.51. As for the shock plates, internet buy for $70 and clamp kit from Just Suspension for $36 and change.
