I have Previously posted questions about 1937 Flathead motor. I am getting closer to Installing it in my 31 coupe. Do I use stock model A rear end and front end? Should I use my 37 running gear ? What is involved in installing driveshaft, torque tube , etc? Any help Will be greatly appreciated. Thanks

You would probably get better answers posting on HAMB (https://www.jalopyjournal.com/forum/forums/the-hokey-ass-message-board.5/) as this site and Fordbarn.com deal primarily with original cars. Having said that I would suggest as follows: Keep the original Model A front and rear ends. Convert them to hydraulic brakes using early Ford (least expensive) or the reproduction early Lincoln brakes (best). Remember you need adapters to run the original Model A wheels or any wire wheel thru 1935 (Including the Kelseys) on these drums. Keep the original spindles and use a kit to add the hydraulic brakes. They make a master cylinder mount that is built into a beefed-up battery box which I believe would work. When replacing the Model A transmission, you will need to fabricate a mount for the wishbone, there is probably a kit to do this. The ’37 front, and rear ends are slightly too wide and the driveshaft would need to be shortened. Of course if you can’t keep your foot out of it, the ’37 is a stronger rear end.

If you are willing to go to the effort and expense of converting the Model A to an open driveline, you can use a Chevy S-10 Borg-Warner T-5 Manual 5-Speed Transmission with a Ford 8" Rear Axle. The rear axle will come with Hydraulic Rear Brakes of 9" or greater diameter drums. The 8" rear axles came in many intermediate size Ford vehicles and are plenty strong enough to handle the power of a Flathead. The T-5 transmissions came in many different GM vehicles - the best ones as far as placement of the shift levers goes are from the small pickup trucks. For a rear suspension you can use a pair of longitudinally mounted leaf springs or a four-bar linkage with coil over shocks. The T-5 has an internal overdrive gear and the 8" rear axles came with many different ratios so you can tailor your car to be an effortless highway cruiser once you make further upgrades to the front brakes and steering system.
