Will a 3 speed ****** replace a 4 speed ******. I have a 4 speed in my 30 A pickup and want to put a 3 speed in it. Please give me details
 
Yes, but you will need a new universal and u-joint cap if I remember correctly. Make sure you hang on to everything you take off, I believe the u-joint and cap are hard to find. I almost forgot to say welcome to Fordbarn!

Do you know of any transmission/engine combos that would directly fit in my existing model a frame
 
Beings it is a pickup it should have had a 3 spd to begin with. Take care of the AA 4 spd bellousing as they bring around $125 if not cracked or have any chipped bolt holes. They are used by many to put T-5 transmissions in Model A's. Rod

Thank you. My 4 speed is rough so I have a 3 speed and want to put it in instead. So I can unbolt my ****** and housing and put the 3 speed and housing right to it? What do I need to order or find to make this happen?
 
Are you taking out a model A 4 speed, or a 4 speed overdrive unit out of a more modern pickup?
 
Change your bell housing to passenger car type; also change the u-joint housing to passenger car type.

As said before, save the 4 speed bell housing, transmission and u-joint as people are looking for these parts and you may be able to recover some of your expense.

I'm not sure if the intermediate shaft will still be the correct length. Is your AA 131wb or 157"?
 
If you go back to the 1st post it sounds like he has an A p/up with an AA 4speed ****** in it and wants to go back to a 3 speed. JMO

There was an option where Ford supplied a regular Model-A chassis with a AA 4-speed transmission in lieu of a 3-speed. I actually purchased a chassis out in the panhandle of north Texas a decade or so ago. These were sorta popular with a farmer that wanted a slow gear to feed out of, --or as in the case with this chassis, there was a PTO and a shaft going out the back to power a belt pulley.

Truthfully, the biggest value that is there is the AA bellhousing that folks like to use when converting to a S10 transmission. Otherwise there is plenty of these conversions still floating around to supply the demand.
