This is a complete shock package that will put modern cylinder style shocks on your Model A. The only extra holes you have to drill are the upper shock mounting holes in the rear cross member. The lower front mount clamps to the axle and does not require drilling the axle. Can be done with body on the chassis. Only complete kits are available, no partials. Shocks are hydraulic not gas. Brackets are 1/4" thick steel and come powder coated.
