Left axle plates are forged steel as OE. Weld-on type. The axle slots are 7\/8 inch on both sides.\n\u003cp\u003eThe V-Twin 51-0781 Replica Hardtail Rear Frame Section is a full replica construction designed for installation on 1948–1957 Harley-Davidson FL models. The section includes forged rear axle plates, an oil tank mount, lower rear fender mount, center tube, engine and transmission mount, transmission mount strap, weldment, tool box mount and top seat post forging. The seat post yoke is included in the weldment and allows the post to be retained with a rigid seat post bushing.\u003c\/p\u003e\u003cp\u003eThis rear frame section accepts a stock-width 500 x 16 tire, mechanical juice brakes, a replica rear stand and a stock rear fender. Mechanical juice brakes require welding an additional tab onto the left axle plate. The tail accepts a seat post, mechanical brake cross shaft and brake drum assembly. Sidecar loops are available separately. The top tank tube is not included, and the section is intended for professional welding installation.\u003c\/p\u003e\u003cp\u003eThe V-Twin 51-0781 is designed for 4-speed, chain-drive applications.
