I got a used steering box for my row rhd '84 d-90 from one of the guys on this site. I had him mail it to meridian for rebuilding. After I get it back and have it installed, my old box will be available for sale if you want it. I went this route instead of removing my current box and mailing it out for rebuilding because I use my truck every day and I didn't want to be without the defender while waiting for rebuild, shipping, etc. In fact, the guy I bought the box from did the same thing. If it helps, Let me know if you need the box. Its a 4 bolt box. I paid $100 plus $60 shipping to meridian and would be happy to do the same... not looking to turn a profit or anything... Just passing on the same cost I paid. Anyway, good luck.
