transmission ID

when i bought my car it had an engine and transmission from a different vehicle in it. i need to get a tailshaft bushing for my transmission but dont know how to order it because i dont know the model of trans i have. it is a older 4-speed manual
the only numbers i see stamped on it are C4AR-7A040 with a large A after that, blow that there is W-2 and a piece that looked like it was attached with screws that had X30 or K30, its hard to tell which
so my question is can i order the bushing with this information? or do i need to know what car it came out of? or at least a model number for it

That number on your transmission doesn't really mean anything it is the casted number and doesn't reflect the transmission type but it does allow me to know the general era of transmission it was built in.

I am thinking it might be a Mustang/Galaxie Tranny from 64-72 or a F150 Tranny from 78-83.

I need to know the following if possible.
Car & Year:
Engine:
Tranny fluid:

its in a 1957 ford courier, i dont know what it came out of
the engine is a 390 FE
dont know the fluid

Four or Six Barrel Carb?
Automatic or Manual?

The 390(6.4L) was stretched from 1961 to 1976 and was used in a damn near ever single Ford built. The problem is they built 8 different varations of the 390 with three different transmissions. But based on the casting numbers you gave I know it came out of either a Ford Galaxie or a Ford Mustang. Give me the top info and I will be able to give you your tranny type.

it has been rebuilt so it has aftermarket intake maniford on it. it is currently a 4 barrel.
it is a manual transmission

Your engine came out of a Mustang and your transmission is aFord Toploader 4-speed.

thank you for the help
