I made a tail shaft extension from a donor 70's 3 speed and machined a tail shaft housing from 6" x 10" round cold roll(weighed 70 lbs when I started and 18 when finished), fabricated a rear mount and installed and S10 rear end. End result, original tranny, 3:73 ratio so the driving experience is still there but 55 is a reality. It all ready has one summers use on it with no problems.

There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

I took pictures every step then learned a valuable lesson about letting my darling wife load film in the camera. The donor transmission gave up the tailshaft so I would have the splines to match the new driveshaft. The otherend of this roughly 9" piece had a spline machine on it to match the old universal joint so I could leave it in place for the speedo drive. These were pinned together and a housing machined with a bushing in the front to carry the old universal joint(of course it doesn't universal anymore) and a standard chevy bushing and seal in the rear for the new driveshaft. Stock 38 tranmission with new open drive line. If you want to consider doing this email me and I'll sketch it up with dims.

If so,back in the late 50's before good floorshift kits like Hurst, hot rodders used the top shifting old tranny cases like your,adapted the 55 and up tailhousing from a Chevy 3 spd for use in open driveline cars.I belive the mainshaft from a 55 and up Muncie 3spd will more or less fit into the older transmissions.it might require some machine work.Its great to hear some guys like you are still daring to be different. | | |
