Re: swapping in a saginaw 3spd OD..need info

That's a Saginaw 3 speed with an R10 Warner overdrive from a 1968 Chevy car. Now look at the spline area of the input shaft and see if there are any 360 degree "rings" . Most likely there will be a single ring for the common 2.54 1st gearbox from behind a 307 V8 car.
