9" drum to disc conversion confusion

I think that scarebird kit looks quite shady it doesnt have the authenic look or strength...

Scarebird probably isn't an option for you since you have already collected other parts, unless you decide they won't work (many report fine results w/ FMJ spindles). I wouldn't be concerned w/ Scarebird's design. It looks very strong to me, and I am a mechanical engineer. Forces on a caliper are fairly predictable since there is a built-in force limiter in the tires sliding.

I haven't heard of the 9" drum spindle failing, as one post reports. Certainly it could fail in dirt-track racing or such, but unlikely on the street as designed. I did have the outer bearing spin the race in both hubs on my 69 Dart, so that is probably the weak point. You can go overboard putting the heaviest brakes imaginable (C-body disks?), but then you lose the light-weight feature of the A-body. Ditto for sub-frame braces and such.
