Transmission question
I have a 66 F100 SWB with the original 352 and 3 on the tree. The tranny is going bad. Will a top-loader 4-speed bolt up to the 3-speeds bell-housing? I'm talking about a car type 4-speed. I happen to have one from a 65 Mustang. Will the shifter be too far back for use with a bench seat? Anyone else tried this?

I'm getting ready to do the same thing, my top loader is from a galaxy and I have no bellhousing from the galaxy. I do have to replace the 1-2 shift cam in the 4spd, found a great source for parts:
David Kee Toploader Transmissions, Inc..
He also list a hurst shifter for the trucks. I can't imagine the stock shifter is going to fit. Let me know what you find out. I'm pulling the 352 and 3spd out this weekend. I also have a donor 150 with a truck four speed behind a 302, and the original 3 speed is in good shape, so I have three options.

The top loader is an AUSOME tranny !!!! you can put a lot of hp into it and git alot of service out of it . if you have access to the tranny, count the splines on both the input and the output shafts, make shure there the same(if the output isnt you can find a parts store to match the first u-joint, if the in put isnt you can most defenitly find a clutch). as for shifter,..... it is an external system, hurst or another will offer the placement you want.
But... I think what you were asking was what bell housing will work? as far as I know there are four mesurements you must look at for total tranny hook up.
1 Input shaft length
2 input shaft diameter, pilot, tough out berring and clutch spline
3 input shaft spline- spline count
4 tail shaft length ... trannys differ so mesure the length of tranny
5 output shaft spline- spline count and dia.
6 out put shaft diameter
7 tis is the one that screws me up every time, the tranny centers itself on the big hole in the bell housing, that dia. has squred me more than once.
8 speedo hookup
ok Im drnk
theezs are my 4 things too look at when switching trannys
ok possably 8 things.
can someone put it into simpler term than I?
GOOD LUCK ,
