[Roadsters] brake bleeding woes

I had read somewhere on the List or Forum that a someone had  pulled the 
axles and reversed them so the bleeders were at the top. I think I have a 
pic of that somewhere. I was going to do it to mine the next time I have to 
service the rear wheel cylinders or axles. Unfortunately this was after I 
had already rebuilt the rear axle and brake system. I don't want to take it 
all apart just for that. If I remember correctly he had to rebend some new 
lines going to the cylinders and modify the parking brake linkage since it 
was moved to the front of the axle.
