More questions concerning conversion of
a c-4 to a toploader in my 65. First will
the c4 trans crosmember work with the toploader. Second will the current spacer plate between engine and tran work. Third,
will stick shift clutch brake pedals work in the same under dash bracket as the automatic. ie. Do I need to change the support bracket or just install pedals in the bracket that is in the car.
Anyone with some experience in this ???------------------

I know you'll need the standard pedal hangers, the geometry is different. The engine plate is different from standard to automatic. ------------------

The crossmember is the same for stick or automatic on 65-68 Mustangs except for the C-6 big block cars. The only differance between the block plates (V-8's) is the starter hole. You can cut and splice it to make it work as they are getting hard to come by and rather pricey.  Alex------------------

Scott,
the pedal support of a manual shift has an extra clutch stop bolted to the side and it has a clutch spring bracket bolted to the front close to the steering column, other than that they are the same. If you can find any manual donor would be the best way. As they said previously, the cross member is the same, even the trans mount is the same. The spacer plate is tricky if you don't watch. The 302 from 68 up used a wider plate and bell housing for the 164 tooth flywheel. 65-66 used the 157 tooth and narrow plate and flywheel. I did some comparisons between starters, manual vs auto. It seems that the automatic bendix sticks out farther at rest than the manual. I spent a hour or so at the parts counter of AutoZone comparing them. Does the thickness of the flywheel vs flexplate constitute this, I don't know, just an observation.
Good luck,
Mike

You are absolutely correct. The bendix is longer on a starter designed for an automatic trans. The difference: ringgear distance aft of the crank flange, flexplate vs. flywheel

I guess I should have provided a little more
info as the engine in the car is a 77 or 78
302. The starter I am currently running
is from a 80's 5.0 and is physically smaller
and more powerful. Do you think it will
work ?? Thanks for the info so far.------------------

I minor clarification is needed here. ALL 65-68 small block Mustangs/Cougars had a 157 tooth small bell housing and flywheel. Most of the intermidiates and compacts(Fairlanes/Comets/Falcons) did also. By mid 1968 as the 250 six became more popular, the larger bell housing began finding it's way into the intermidiates. The full size cars and light trucks with 302's or 240 six cylinders from 1968 up began to use the larger 164 tooth flywheel and coresponding bell housing. The larger bell housing and flywheel was not installed behind small blocks or 250's in the smaller cars untill 1969. The small unit was discontinued after 1968 which is making it increasingly difficult to obtain both for stick or auto. Note: I am always seeking small C-4 bell housings. Alex------------------
