Spoon, I've seen the Haynes manuel sold at the local parts stores (pepboys, autozone and a few others). If your looking for Clymer only, I would call the parts stores and see which one they carry. Good luck!!
I think the Clymer is 2nd only to the FSM. I got mine brand new in plastic on ebay for $15 shipped. The guy admitted to me that he lost money selling it for so cheap. I have all the manuals and would rate them:
So search ebay, I was lucky and nobody else bid on the auction. I can't remember if he spelled something wrong so check a few different spellings like datson or clymar.
I have the FSM, Chilton, Haynes, Clymer, Autobooks, and a really old Clymer that only covers 240 & 260. Best bet for good info is the FSM. Most of the diagrams in the aftermarket manuals are identical and a lot of the procedures are the same, too. Information content is pretty uniform throughout all aftermarket manuals. Every now and then you'll find that one may have one key fact about a procedure or part that the others might not have, or might have a better diagram than the others, but for the most part, as far as I've seen, they're all about the same overall...
I got all of mine off of eBay for very low prices.
Also get the how to restore Z cars book and how to modify the L series engine book. These aren't the exact titles, but you'll find them referred to often here.
