Has anyone tried this?

I installed a 4sp OD in my '37 using one of the aok adapter plates. Very few modifications, but it worked like a charm otherwise! Now I'm without my emergency brake though. I had a thought that if I could remove the drum from my 3 speed and mount it at the rear axle I could rig up a mount for the brake shoe band and be back in business.

I got as far as removing the rear pinion seal as the collar on the drum where the seal mates is smaller than the one on the original rear flange that I removed. I think if I can get the right oil seal in place I can figure out the rest. I believe the seal actually holds in the bearing too, so I am a little concerned that the one I get from the parts store will not be robust enough. Has anyone successfully made this modification? Any help would be appreciated.

The U-joint flange, not the seal, retains the bearing. Chrysler faced the same problem in 1936 when the Warner T86-1A overdrive transmission proved too long to mount a parking brake. They moved the parking brake to the rear backing plates. The 1936 rear end used with O.D. was hypoid so these might work on a '37. They're out there but hard to find - Desoto and Chrysler had them in '36.

A friend used a disc from an industrial machine with its mechanical caliper on the rear axle input shaft of his 31 Dodge.  I am sorry I cannot be more specific as to what it actually is.

I was thinking there use to be a custom disk ebrake set up in the speedway catalog.

yes...I have seen this in the past but I have looked about the internet and have come up empty handed...I am also thinking that the unit would have to be used on a pinion housing that is drilled and tap for at least a pinion snubber application..

Yep, that's the one. I hadn't had a speedway catalog in years, surely someone still caries it, seemed pretty useful in custom applications.
