Rear upright assembly

[Oscar]

Aaaarrrggghhhh!!!!!

Trying to find out how to assemble my rear hubs/uprights and finding nadda!

I've got a set of off-verticle rear uprights (compatible with both drum and disc) and rear hubs off a disc-braked sierra.

My question is this: How should the uprights be alligned (leaning forwards or backwards?) and where should the caliper mountings be pointing on the hub once attatched?

I've spent an hour searching through posts and using the search fuction and found almost nought! Did find one brief post saying that the uprights should lean back on a drum brake system, but thats it!

Am I being dense? Not looking in the right place? Any help to aleviate my frustration would be greatly appreciated!
