They had them for lower recently like $72 or so, they do take best offer but as I had said before don't put in best offer, write them via ebay email ask seller a question, ask them what the lowest price they'll take is and they'll tellyou and send you a checkout link. I tried best offer and they kept refusing it. I had asked them before and they said they'd take $122 shipped they were like 82-84 or so and they accepted and sent me a link for $122 and I didn't have the cash. When I did get the cash and tried best offer it kept kicking it, I wrote them and they said here's a link, sent me a checkout for the 122 shipped. So IMO they kick every ebay best offer, but write them, they'll tell you what they'll take.
Plug clearance is tight, need to use a wrench on the back 2 on each side, aa cut down shorty socker for plugs, or an offset 5/8 would do it. I had it done in less then a day, maybe 4 hrs or so if that.
