Putting discs in a early front axle

OHeh no easy task in here...i though to put the discs in the 1970 bug, but had to back off because the bad interchange for some parts... The bad part was that i had adapters for the saddles from a early front axle, but it seemes that the bolt pattern is different so i put the drum brakes back to the bug...

Ok whats next in the yard? A convertible 1965 ghia...ok, off the drums and in here the adapters for the saddles bolts right on... Then the discs, no way the bearings have a big missmatch, looks like i need a trip to a machineshop, with the discs....the easy part would be to swap to the dropped spindles...that would be the easy part, because i have those in a box. But i would like to know what must be done with the stock ones to suit...

To be continued...
