What shape is the male gear on the end of the transmission output shaft
and the female gear on the coupling shaft in? This link may be the U-joint
you need. http://www.fordbarn.com/forum/showthread.php?t=4171

I think the 1937 is a little easier to find and it has good breakdown
of the units also. Ebay has them. http://cgi.ebay.com/ebaymotors/1928-193 ... Literature

I don't have any extra parts Johnny. I bought a long wheel base coupling
shaft from Neil Wilson a couple years ago, he may have one for a short wheel base.

This one is good. http://www.brattons.com/product.asp?P_I ... &PT_ID=all

Sounds like a plan. Here is a pic of the parts for the coupling shaft.

Are you going to keep the Dual High or take it out and
put in a longer drive shaft? If you are keeping the Dual High
they made a U-joint that bolts to the 4-speed and has the
correct splines for the Dual High.

Mike, You'll get a much better fit if you take them to an
automotive machine shop with a Sunnen hone and have
the bushings honed.

Bob

Neil, I think what is on the back of the 4-speed is a cut down front support for the coupling shaft housing (AA-4810). The u-joint seems to be sticking out to far from the back of the transmission. I wonder if it was welded to the coupling shaft male gear (AA-4811) like they did to the drive shaft c...

Really no room for a bearing. Everything looks pretty good from the pictures, kind
of hard to stop the leaks the way they shortened it though.

Bob

Manyolkars, I made your pictures a little smaller.

Hi john, There is a coupling that connects the drive shaft to
the pinion that could be worn or the u-joint between the Dual High
and the drive shaft.

The AA steering arms are different but the balls are the same size as the A, and
the pitman arm is the same as the A. A&L can put new stainless balls on your
old arms.

Bob

Thanks for checking Shelby.

They unscrew.

This what you need?
