I have a fiberglass cowl hood. I have had it for about 3-4 years and havent had a problem with it cracking or any other problems. I have it latched down with hood pins, this way I can take off the entire hood to work in the engine compartment, makes it alot easier when you can stand up in there /forums/images/graemlins/wink.gif, the hood only ways about 10 lbs, so it very light. Its probly taken about 30-40 lbs off of the truck weight when you consider all of the hood springs and latches that are now gone. /forums/images/graemlins/thumb.gif. I thougth about doing fiberglass doors but Im not sure if I will or not.
