Long story short, I had to replace my rear axle, and silly me, the axle I picked up was from a 740 wagon, so now I have a very noticeable rear brake bias.
Should I find replacement stock calipers, adjust something, or upgrade the front brakes to match?

 

okay, the new rear end I put in with the wagon rear brakes just seized, due to my dumb *** not checking to see if it had oil in it. now, my friend paulmer is suggesting I try a bolt-in independent rear suspension replacement. supposedly the 760 and 960 independent rears just bolt in on a '91 740.
suggestions / comments / concerns / anything?

 

No they don't, and you'd be opening a whole new can of worms...
