I did email, but they are for pre-99s so they wouldn't fit.
I've been looking all around for bumpers for a 99 Tracker and there's not much. Freight is also a huge killer, and some outfits (ZOR) are backed up and/or only making 1st gen bumpers. Calmini and someone else also told me their bumpers couldn't support tow bars...which seems odd. AlteredEgo's do, but again it's massive freight and whatnot to the States.
I ran this by the local fab guys and they can probably do something for me in the same general price range, and I suspect that's what many people do. Maybe a more minimalist kit might be the way to go, like AtoZ Fabrication does for jeepers. Just a rectangular tube bent to conform to the various SideTrackers etc, bracket material, and add-ons like receiver tubes, tow bars, winch plates, bull bars, etc. Take 'em to a fab shop or good welder and it would still come in at about the same prices maybe. I keep searching CL in hopes of finding something. I'd just cut off the bracketry and the shop could mount it. For them it's a big time hassle to design the bar to your specifications; easier to just fab the installation parts.
