Painting 944 rear hubs

[paul_f]

I am sandblasting and spraying all my 944 rear suspension parts prior to fitting - is there any issue with me doing this to the early rear hubs? I will protect the threads with tape, but didn't know if there was an issue with the surface where the disc attaches to the hub.

On a related note - any one know what thread and size the screws to hold the disc to the hub are? Neither of my hubs had the screws - I know this is no issue as the wheel and wheel nuts hold them on but would like to have all parts present.

Thanks
Paul
