I guess I could actually understand that.. if someone has a marginal box, and then orders a "rebuilt", pays the core and then decides to keep their "marginal" box as a spare, then pretty soon their rebuilt-already supply goes away. they are still an option for me, I just have to get home and pull my box first... but that disables my truck until I get it back, so will likely not do that until I get the truck to my own house, instead of my Brother's in Arkansas...
Thanks for that update... I'll book mark their page for reference anyway.
