Default 1940 Pickup clutch linkage

I need to adapt from a 1940 clutch linkage to a 8BA clutch fork out of the 8BA bellhousing. I'm sure some of you have done this and can give me a head start on figuring it out! Did you fabricate a arm for the clutch pedal or a equalizer shaft similar to the stock 40? Thanks for your help, Dale.

I guess you want to make a 49 car bell housing to work with 40 linkage.
I think you will need a hydraulic pull or push setup.

I welded a new arm on the clutch pedal boss. It was a 45 Ford pick up with a Chevy engine trans. Works fine. I could post a pic in a few days. Not my pick up.

If you are using the hogs head bell should be like the 40 horz shaft.
The 53 truck is a pull to rear same as car 49 53, juice is the way to go.
If I remember the 86 ford 3speed with od ford used juice clutch.

I was going to say the same thing deuce, a photo of the bellhousing you are using would be very helpful to understand what you are attempting to do.

It is a stamped steel 8BA bellhousing with the top shift F-150 4 speed attached. It uses the regular 8BA clutch fork. Thanks guys for your help, Dale.

It would help to put the lever side in the pic.
I guess it 49to53 car housing.
What you need to do is pull the lever to the back.
If you take a piece of medal and make 3 holes say about 1" apart the middle is the pivot.
By pushing the bottom hole forward it pulls the lever to the back to work clutch.
If you used a 39 pedal would be better to hook together.
With the small movement on the 39 a one to one maybe to small you may need say another 1/2" up top. So you encrese to 1 1/2" top. or shorten the lower hole.
Mud right.

Thanks George, it is a 49-50 stamped steel housing. Sorry I didn't have a picture of the other side on my computer. I know what you are saying and the reason I posted the question I hoped someone had the right measurements so I wouldn't have to experiment to get the right ratio. Thank you for your help, Dale.

I had a 86 f150 with that trans 3 speed with over drive, I liked it much better then 4 with od. I think they were made only a few years. That's a nice compo with flathead.

May not want to hear it now, but you might have been better off with a hogshead. It has the linkage that would bolt up to the existing clutch pedal fairly easily. The bolt pattern on that transmission looks similar to a T5, so it would probably take the hogshead plus an adapter plate.

That is an option but too many adapters for me. This one is easy the two bottom holes line up and add two ears for the top holes. Thanks, Dale.

Well, one adapter, but that's water under the bridge!! LOL That is the method I used on my T5, it sure makes the clutch setup slick. Your best approach might be a slave cylinder master cylinder approach (if the current method your trying doesn't work out}.

Linkage and floor pedals something like shown is about as simple as it gets, and easy to fabricate. The drilling of extra holes makes dialing-in pedal-travel adjustments a piece of cake. This is your basic '40 Ford-type frame. DD

If you keep the 40 linkage you have to steady the end of the horz shaft.
Then get angle iron and bolt to trans 2 bolts left side.
Make parts as shown.
Don't worry about pretty you can always chrome later.
Just get it to work first.
This should work.

If you have a piece of angle iron 3"x3" 6" long its bolted to the trans bolts.
The flat surface goes front to back. 3/4" hole for pivot.
Make parts as shown.
The is a 53 pu trans bell they have ears for engine mounts not like 50 car.
Just bolt to left holes
You only need about of 1" travel drill hole in best location on angle iron.
