Okay then, I'll give it a shot tomorrow...when we (myself and the two guys who were going to spray the liner in) tried to do it at the shop today, they didn't have enough extensions to get in there at the bottom one...the top was no problem with a deepsocket and a short extension, though. The bottom...well, I've got at least two 12" extensions and probably three 3" extensions. That should be enough.
I really oughta buy a universal one of these days...I have some universal sockets, but they're metric!
