Snicklefritz,
Absolutely nothing wrong with running drum brakes all the way around. Most all parts are still available at a reasonable cost. The one exception as you have found out is the backing plates. Don't despair as they are out there but it does take a little searching to find some of them. We needed to build front and rear drum brakes that would take 4" wide linings. Also needed the drums to be aluminum with iron linings. These all needed to be based off the 59 era Mercury/Ford 9" brakes that were never a production part. Cast the the aluminum drums. Two separate casting has there was a difference front to rear. Rolled the steel bands and lazer cut the inner rib that the springs attached to. Built a simple welding fixture to hold the band while welding the rib in place. Ordered a cast iron 12' diameter pipe ans sawed if in to 4.5" rings. Machined them and the inside surface of the aluminum drum to a press fit. Then staked the two together. Bought the wheel cylinders, adjusters and springs. Had the linings bonded and riveted in place. Bolted it together just like a family sedan. Found the early backing plates after a short search up in the Midwest. Bought all he had as the fronts were the hardest to find due to spindle changes in later years. So if we could do that then you can surely find what you need. Drum brakes in a lite weight roadster will be more then enough to stop you. And in my opinion they look great painted black behind a chromed wheel. If I ever figure out he photo posting secret handshake I will post a few pictures of those brakes in construction. Good luck with your project and have fun while you can. Getting old ain't for sissies!

You only need 10 post before you can include pics. This has been a known problem for a long
time. It's sporadic and it comes and goes, even for the same person. It's happened to me and then
one day it was OK again. Ron is not a website guy and it probably costs too much to hire someone
to fix the problem.
I am administrator on another forum (same Xenforo software), I might be able to help if I had the
required permissions.

that there may be my issue. not sure what i have so far but at least it may be that and not just that i'm thick headed. *oh wait a minute... as i type this i see a button for uploading a file. i'll experiment later.
am i to understand the forum was set up by ron of rpm? i should mention that while i find the situation only a bit frustrating (i've no build thread yet) the overall format is more welcoming than the ntba forum which may just serve as a back up of sorts for the club. thanks for your input sir!

No Ron didn't start the Forum but is a co-owner if I am correct. No he doesn't want to be an IT tech just like the rest of us old guys But some things you just have to learn or go hide under a rock and wait to die.

It's about 54 inches from center to center of the kingpins.
Just put fatter tires on the rear and skinny ones on the front-- or better yet get another axle. Yours would not be the first like that as people used what they had or could afford.
