I stuggled with this one for quite a while. Knowing the best location and bringing yourself to doing it are two different things. CB radios and Amateur radio equipment is two entirely different animals though. I run a Kenwood 742 on 2m, 1.25m and 70 cm with 60w, 30w, and 38w and an Icom V8000 with 80w forward power and my gain antenna it gives me and ERP of 103w, 68w, 107w and 137w. I drilled the center of the roof. It still hurts sometimes but its done. I temped in a pine type box to mount the two radios in, have changed the design a few times and am just about to build the final design out of buryl to match the wood accents of the larriat. Several coats of high gloss lacquer and it should look factory. It sets on the transmission tunnel as I just can't bring myself to drilling holes in the dash.
