We will have at Bakersfield a small drum Ruckstell adapted for 27 wire wheels. Built by me with Timken pinion bearings, Rite Way sealed axle bearings, 3:1 gears and small drum brakes. $2100, ready for your speedster project. Would cost way more than that to build a new Ruckstell or rebuild a junk swap meet unit.
Add this ruckstell/rear end to the chassis components in this thread and have a complete assembly.
Ruckstell has a new home. Thanks MTFCA
