I've been running/Drag Racing the Saginaw 4 speeds for four years now and finally found a Super T10 with a 2:88 1st Gear that I could afford. I now have to disassymble it and have the gears Face Plated or Pro Shifted by Liberty Gears. I've 'Crash Boxed' the previous trannys myself and look forward to Liberty's services. I will post pictures as this project moves along.
Are you going to have them improve the lubrication of the gears too? The super T-10 is prone to galling due to lubrication issues but there are some things that can be done to improve the oiling of the gears and shafts. The mods make the tranny live a lot longer than without it.
