I trusted the guy to sell out of ebay as he had tons of positive feedback, did him a favour by saving listing charges etc, and he sent me the wrong items. Was just a pair of Rover 200 REAR door handles I was after as they fit my CRX, but have no keyhole you see. Im about to delock it as it was broken into the other week- stock CRX door locks are about as secure as a Metros... Ive done this a few times and had no issues. He is now not returning emails after sending one rear and one front handle. Ive been resonable and offered them both back so he can resell to someone who needs them... arsehole... Im just to much of a walk over I guess.
I do have his address though

. Silly boy he is! I have developed something of a mean streak for tossers like him. I got me a set of brand new rear handles in the right colour for the same price, so now its just a case of deciding what to do to him/send him in the post... hmmm wheres that poop-a-scooper bin...?
As for your issues mate... bummer. I dont have any 2wd specific parts Im afraid, and I only have 2 hardened diffs and Im using those. Ive got some stock ones kicking about if theyre any good (not really I know, but they will work for a bit...?) LHS with Cen hardened diffs in the UK? You know better than that! Pants innit. Let me know about the stock diffs though.
