These 10 degree spindles will fit 3rd through 5th Howe chassis as well as stock clip cars. They are all 8-3/4" tall with a 3-1/2" pin height and are built for 1-1/4" thick 11-3/4" rotors. The standard 5" width pin will give you a hub to hub width of 64-1/4" with Howe 5x5 hubs on a Camaro clip with stock length lowers. Wide 5 hubs add 1". Spindles narrower than 5" will require modifications to the lower a-frame to clear the rotor.
