I saw this topic yesterday and bought one, or so I thought, as the seller emailed me later claiming "clerical mistake". He's not even claiming responsibility for the error, like his auction just magically appeared and he has no idea how the mistake was made.
I emailed him a link to eBay's Help site about non-selling sellers which I think is making him think twice about just blowing me off. Also, his ad says he had/has 9 available (was 10 when I bought 1) he's just quoting what "his supplier" has, he doesn't personally have them in stock.
I figured for the price I'd take a chance, but I'm not sure I want to take it further unless I know this adapter does, in fact, work on TIV motors. I have no experience with 356 motors. Anyone, ? Thanks, Bob
