As for the p/s issue for the box, I bought an old cast spacer adapter a while back off of ebay. Haven't used it yet, but it adapts a 73 and up chev steering box and pitman arm to the existing front end-do a little searching(I know ebay's sometimes a copout, but I've seen other types of kits) and you should be able to dig something up. Unless yor truck came with power steering, of course...
