I installed your (64-67) complete disk brake kit on my -57 bus (with late model spindles + IRS application). The installation was totally painless and everything fits like planned so THANK YOU! Also support was 10+.
I have ORIGINAL early Porsche Fuchs (4.5x15 & 6x15 deep sixes, with hearts) and before i ordered your brake kit i was asking about the fitting... You told me that you are not sure if they will fit and probably would need spacers.
So just to let you know (if any other customer asks): The WILL fit and if you put 2mm spacers the original center cups will fit also. I ended up to grind 2mm off from axles and now the fit like a glove!
