Typically the problem with using a grill gaurd on a Renny is that you must sacrifice the tow hooks as this is typically where most of the guards mount. Also, most guards are not built for much more than "light use" and will not provide any type of mounting locations for tow hooks, or even provide a strong enough point to anchor a tow strap - even for highway use.
I think there are a few suppliers making guards for the Libbys, though I haven't seen many I like. Most seem to hi-light the "frog-eye'd" look of the earlier models.
The link was great! My problem with shopping on-line so far has been I have to wonder when I see things listed for an 06, and the picture is for an earlier 02-04, or as some of those show, another vehicle all together...
I would be interested in the 7th or 8th items by RAMPAGE, but there again, an installed picture could make-or-break the deal. The sad thing is I'd be dropping $160 (more for chome) plus whatever the mounting kit costs, plus any shipping, only to find out if I really like it or not. Don't get me wrong - mail order can be great, but I usually try to find a local retailer to go have a look first...
Hopefully someone here may be running one and can help you out. It's a grat place for that....
