She's coming together! Subframe and rear diff are installed. One thing I nearly missed was having the trailing arm bolts in the subframe before installing it. With the wheel well liners in I don't think that bolt can go in afterwards. The subframe itself is black, the brownish colour is just a result of grinding some rust off other parts. I'll give it a wipe down before installing more stuff.
One thing I had to do was chase all the threads before installing the new fasteners with anti-seize. I'm not too keen on taking a chance of one of the bolts cross threading, as many of them weren't all that happy about going together. New fasteners are awesome though! No chance of rounding any rusted/swollen heads.
