Thanks for the comments Terry,
The hubs /bearing donors are AUDI A6 or A4 , European models:
*Rear is a 82 mm OD bearing - Hub as shown on the picture , with a 38 splines drive, in order to match with VAG Transporter half-shafts I plan to install .
Bearing holders are still to be machined from 7075 ally....
*Front are 75 mm OD bearings , smaller hub , and similar bearing holders than rear
All this stuff may be a little bit heavy , but it should do the job ....
