i have to admit. i hated cowl and HD. but i have warmed to them both. i say do an 06 front end on your truck. that would be sweet. the 06 hood has an HD feel to it. without going overboard. i have been thinking about that for mine. i would have the only charcoal grey metallic 05 with 06 grlle an hood. but if i were you id prolly go cowl. if i had to pick one.
