rear calliper spacing
 

sorry guys, i know this has been covered before but im still confused. i noked up some rear uprights in the drum orientation, then bought some adaptor plater from 3g to convert to disks. the first question is do i need to mackine down the original calliper hanger ty the thickness of the plate.
also before i finish weld the uprighs completeley are the book drawings correct as i have seen people mention callipers mounted at 45 degrees before,

cheers guys

lush thats how mine are set, cheers fella

anyone got any thoughts on millin the hanger down to level it up with the disk or is it fine like it is??

I have also wondered how you compensate for the caliper being mounted further forward on the adapters? I assumed the sliding range of the caliper can cope with it, perhaps there's plenty of play either side of the pads? I also looked at a few pics of the proper disc hubs and the caliper carrier mounting holes do seem slightly raised in comparison to the hub bolt holes.

I am half tempted to just use my drums I got with my drive shafts and ditch rear discs for now, I am a little worried about the front/back bias of the brakes when using rear discs. Especially after AdrianH had trouble with rear drums locking up too soon.
