Got the housing cleaned up. Cut off and welded up the P/S ports on the rack housing and plugged the ports on the pinion housing with QuikSteel (no TIG and couldn't find the right bolts).
I also welded up the pinion but my welds kind of suck so I'd rather not share that picture on the internet. I just need to find a way to paint the housing (too damn cold!) and I can put everything back together again.
I also started to mess with the TII side skirts I've had lying around for over a year since I'm going to do some body work with this build. I bought the side skirts second (or third?) hand so they're missing several clips and things, which are NLA from Mazda. I'm going to have to be a little creative to install these...
