Looking a bit deeper at this, is there any particular reason to use the 2006 version (pn12580420) over the 2009 version (pn12620308), or vice-versa ?
There are a couple of physical size differences, otherwise...?
My son has an '06 TBSS and has found the guys at the link I provided to be very helpful. You should give it a try. At least you'd be talking to guys that know as much, or more than the S10 crowd knows about S10's.
They use the same forum software as we do, so getting around would be familiar.
