i've seen it done a thousand times and i've seen them crack 999 times..i have a 70 chevy shortbed stepside..im changing to a 68 frt clip and would love to put a teardrop scoop on it ...but worried about crackin...would it help if i cut the hood out completely under the scoop then sanwhiched it with cloth ..and even run strips of cloth from the scoop onto the bottom of the hood from underneath??

It could do , the cracking is usually a result of excessive flex in the bonnet itself , ie inner frames removed etc , try to keep as much of the original bonnet framing as you can , ie welding a "end" into any framing that is cut through around the opening , running the glass from inside of the scoop and blending into the underneath of the bonnet would more than likely help the cause with the added ridgity.

thanks...also thought of welding in some gussets around the hole to keep the hood from flexing so much

good idea , just remember not to get to much heat into the skin itself as you have a big job ahead correcting the distortion :)

I put a fiberglass on my elky and it cracked after a few years.The problem as I understand is the fiberglass scoop ,filler,and steel hood all heat up and cool down at different rates wich can cause the cracking.

I put one on a '55 chevy steel hood that never cracked! I know, you want to know how! It was one of those harwood bolt-on scoops with the rubber gasket around it! The car was black, and until you got real close, you couldn't tell!

The best way is to get a fiberglass hood and bond it to that, steel to fiberglass will always crack eventually.
