guys, i reckon you are going to be pushing it uphill to get 20 orders although that is a very reasonable target set by the manufacturer.

for all the reasons i have mentioned in other posts & speaking form experience I still reckon the best way forward would be to develop a kit do make a doubler.

I'm talking independantly to NWest Fab about their unit & I have to do some measurements this weekend.

But given all the experience & knowledge on this forum , especially the guys who have actually fitted doublers a team effort may be the way to go instead of indivuality.

I would be willing to chip in $$$ to get the project started if others are interested as well. Otherwise I will probably go it alone with the Black Box untit & try getting adaptors made here locally in OZ.

cheers
