I know that this has been "talked about"... relocating the drive shaft from the factory position to the emergency brake drum.
With the assistance of Automotive Supply in Livonia MI, I was able to find a yoke that had the spline size I needed... with the U-Joint size that is stock. But here is the kicker, I do not have any emergency brakes.... YET!! I am in the process of having an adapter plate made to use the old yoke and brake drum, and install the new yoke.
Everything tight and double checked, I took the "Meat Wagon" out for a spin and some much needed fuel. WOW!!!! OMG!!! Where did the noise from the transfer case go???? What a difference relocating that drive shaft made. The is no loss of performance or loss of 4 wheel drive if needed. Again, WOW!
I contacted Vintage Power Wagon to see if they had any "Kits" available, and the answer was NO. So I removed the brake drum and yoke, went to Automotive Supply, and a very nice person named Tim looked in their considerable stash of old yoke and such.... and actually found the Detroit yoke that Vintage was selling. Here is the problems. 1) The spline was perfect, however the U-joint was 5 inches wide!! 1a) Try to find the U-joint retainer straps.... Tim says he hasn't seen them anywhere for about two years. 2)This forces you to buy the 5"X1 1/5" U-joint. 3) Because of the larger U-joint, you now have to buy a new drive shaft yoke.
It is true that those parts were a true "bolt on"... it is also true that they are almost impossible to find.
So anyway, the company that is making me an adapter plate is going to try to "give me a break" on design and manufacturing. I'll let everyone interested know how this turns out.
