Technical 32 Chevy open drive conversion

So my 30 Pontiac roadster has a 32 Chevy frame with all associated 32 Chevy running gear except for the Stovebolt which is a 52 216. The 32 Chevy three speed with freewheel is attached to the Stovebolt with a homemade adapter. Going forward I’d really like to have the opportunity to switch out enclosed drive for open, however being a period build my intent is to keep the mechanical brakes so swapping out the entire rear is out of the question. In following some of the conversations here, I’m aware that mid fifties open Chevy rears interchange directly into the rear housing of earlier Chevy vehicles. Does anyone have any knowledge of how far back that interchange capability goes.
From some of the images I’ve seen, my 32 ten bolt dropout appears to have the same shape and bolt pattern as the later mid fifties open rears. Would be a simple and straightforward resolution to converting my car to open drive. Anybody have any experience with a swap like this??

 

I looked up the gaskets. 25-32 are a different part number from 33-59. 55 and newer were open drive

 

Thanks for making the effort! I didn’t consider doing that, where’d yah look those up?
I didn’t think that there’d be listing for something that old except for the restoration type suppliers.
Back to square one!

 

So mechanical brakes are ok
But not digging the enclosed DS
Cool beans

 

Gotta ask why?

 

I just googled 32 chevy rear end gasket

 

Found it, the filling station shows the different gaskets, thanks 33an a3rd

 

Why the open drive? Not that excited bout the freewheel device nor the difficulty of servicing the closed drive. Not that comfortable as well with the homemade trans adapter long term.

 

the rear chuck swop would be just a small part in the conversion, transmission would have to be swopped or some kind of adaptor for the tail shaft. if the tranny gets swopped, are the pedals mounted to it? it is a lot of work for NO gain. swopping out the freewheeling tranny for the next generation would be helpful

 

Can a later version torque tube tranny be used?

 

So I really like the vintage aspect of the mechanical brakes and how they fit with the theme of the car. We’ll see if I scare myself as I get some seat time, maybe I’ll change my mind. I’m not seeing that development at this point.
50 years of spinning wrenches I’ve never had the opportunity to work with or service a closed drive system, possibly that’s part of my discomfort? However as I see it, an open drive swap opens more possibilities in rear end ratios and trans applications as well as ease of serviceability. I’m aware that there will be issues with the pedals, that part of the car is already cobbled together to support the installation of the Stovebolt, the bell housing for which did not have the mount for the pedal shaft. A fifties / sixties vintage four speed I think would be a cool swap and superior I think to the 32 freewheel 3 speed.
Seems that there is a fix to my issue as from what I’ve gathered with the help of all here, 33 through I think 35 still had mechanical brakes but apparently will support an open drive drop out from the fifties.
All this is planning for future as my immediate goal is to have the car on the road this spring.
I’ve just purchased two 261 truck engines from which I hope to build a new motor over the next year or two to replace the 216 splash oiler that’s currently in the car.
The car will be on the road this year with its current driveline, paraphrasing a quote which I recently read possibly on this forum, “later might be now”
