I know that's an old post, but I want to clarify that the TacoBox has faaaaaar more clocking options than Inchworm: The TacoBox can be clocked 360-degrees in 5-degree increments.
Really who cairs if it has more clocking options? Most of them are useless positions anyhow. anything more then 30* is all but pointless.
Not to menchion hes looking for a 4CYL DUAL SETUP! I know MCI has been OUT OF STOCK for over NINE FULL MONTHS!
If I were him Id go with a Dual setup to have more options on the trial. Id head over to Inchworm and buy the adapters. and If he really wanted to drop some extra coin then buy Marlins 4.7 gears.
I really feel Inchworm makes a better tranny/crawlbox adapter. For the rear adapter its a wash more or less.
But Jim usually always answers his own phone, and he has the parts instock.
