Begging for help before I pay someone to do it the easy way that I didn't think of:

I have a 2000 Rodeo LS with the factory roof/luggage rack.
I have a full-size Federal Signal Vision (looks like a Vector) lightbar.

FedSig doesn't make a mounting kit for Isuzus, nor does my Rodeo have rain gutters to make it work THAT way... I was thinking that there must be some kind of mounting platform under the fairing at the front of my luggage rack that I could make use of - if only I knew what was there before I tear my rack apart!

Any ideas/suggestions/warnings/etc would be greatly appreciated! (I know I'm gonna hafta fab/rig some kind of bracket to adapt the lightbar's mounting holes to whatever holes are on the roof - but I was hoping not to have to drill holes in the roof)

Thanks!
- Scott
