Old-Stf Harley 36-84 Big Twin bolt in post mount for solo hinge & spring seat

Old-Stf seat post mount. Easy drop in mount eliminates the need to weld on your stock or painted frame in order to mount a seat.
Fits stock Harley Big twin frames 1936-84. Machined from 6061 Aluminum with a stainless steel bolt for securing the mount in place. Snap ring groves in 1/4" increments aid in seat adjustment and set up. The snap ring also prevents dropping the mount inside your frame before tightening the bolt.
