I have a 76 Duster with the original 4-speed OD trans in it. I cannot find a output seal any where for this. The one Brewers lists has a 1.625 id and my yoke is 1.695. Also the od where it fits into the tail shaft is 2.50 and is just a little too small. Its a 30 spline output shaft.

All the local stores carry one with small dimensions. Anyone seen this? If so what seal did you use?
Thanks

I used a National #7300S seal from Advance Auto on my O.D. A-833s.
Same specs as yours.

The seal pictured in the link above is not the actual seal you get. I just looked at my A-833 and verfied the part number stamped on the flange.

alot of the A body OD's I have seen use the 904 sized output , the first year or 2 they were 727 sized , get a seal for a 727 since you have a 30 spline output , that's 727 ...

Thanks guys, I do have a large yoke, I will head over to Advance right now as I am dead in the water without one.
