Technical Closed shaft rear end to open shaft

I have searched can't find, how to change a 40 ford rear end from closed drive shaft to open. In the back of my tire smoked mind, this was common in the 50's? Hope someone knows how. Now on a Chevrolet closed shaft rear you can use a 3/4 ton drive shaft.

 

Easiest is to find a ‘42-47 Ford PU rear. But have also read that other methods work, with machining an adapter and using a seal, etc. pretty sure kits are available, but don’t recall who from

 

speedway has em i believe

 

As Budget36 said, 40's Ford pickup rear end parts... or buy one from Hot Rod Works or other vendors.

 

For converting to open drive Hot Rod Works is the only way to go. Stay away from the cheaper kits.

 

You’ll also have to come up with some radius rods to mount he rear ended once you get rid of the torque tube.

Absolutely spend the little bit extra and go with Hot Rod Works kit. I have had no issues whatsoever with mine. Good quality stuff!

 

As for the radius rods here is one way of doing it. Two tubes one each side from a brackets fitted to the wishbone at the Red dot to brackets fitted to the banjo at the Yellow dot.

 

What I did on the mid engine street lakester built for a friend....All made from parts laying around an some lathe work and welding. It doesn't leak or vibrate but this car doesn't get a lot of miles....

 

Dude I may have to" steel"your idea on the rear ladder bars you made that is a dope idea why did I not think of that. That is exactly the idea I needed. I hope you do not mind but I love the look of that. And it is a period look. I'm building a 32 mid engine potvin blower set up. You can check it out in build threads 32 gbones32coupe

To be honest, the Speedway yoke fits loose on the pinion and can cause vibration. We’ve measured it and can confirm it is oversized. We have heard many complaints from users.

Nice it is

 

Thanks on the heads up

 

Thanks

 

Cool just plain cool

 

It the car is in a lakester build thread here about 5 -7 years ago. unfortunately, a lot of the build photos were lost in a computer fuck up...There might be a few more , I will have look for them. The same car is my avatar.

 

I lucked up - found a good deal on this - Thanks everybody!

 

That looks like a Model A rear end. Nothing interchanges with a '40.

 

It is gathering up stuff for my TT build. Engine 140 mercruiser, T-10, Model a front axle as well as rear axle I wanted 39,40 rear for the already in place juce brakes.

 

If the 40 Ford rear is a truck rear you will need a machinist that knows his shit. In the truck rear the pinion and the driveshaft was one piece.

Other wise you can get the parts you need from Speedway as a kit. I know that is whimping out but it is the easiest way.

 

Thanks and its a true story, go back up a few posts. Then you will see the way I now going. Found a super deal on converted to open shaft model A rear. I guess I will convert old school 40's backing plates ect. to juice drum brakes.
