I have a newly overhauled Piper Comanche Gear Transmission made by Dura removed from a 1964 PA30 Twin Comanche and freshly overhauled by the craftsmen at Webco in Newton, KS. I have attached a copy of the overhaul invoice showing a new jackscrew and release arm assembly as well as pictures of the newly overhauled unit. $4,500 Outright.
