got my large L-88 hood scoop in from unlimited today, very happy fits good quality is good, back in the day we fiberglassed these on, has anybody used any modern tech, on these like using the stuff gm glues camaro doors together with, and glues door hinges on pick ups

that glue is definetly strong enough. .i wonder how you would clamp it down till dri. probally have to just put weight on it. id glass it if it was me . or epoxy the bolts to the scoop and bolt it on and use the 3m tape they supply

Not sure why you didn't go with the complete glass hood, as with any add on scoops they will at some point show stress cracks due to flex and heat. back in 1972 I had mine riveted and epoxy filled but on hot days you could see if you looked hard rivet heads under the paint.you will still have to cut the hole in the hood.
I went with the complete glass hood this time no issues just prep and paint
it is perfect in fit and finish

Hope yours works for you

the reason for going w the scoop on the stock hood,is wanted to keep all the factory rubber bumpers,and rear hood seal,along w factory latch, scoop wont be functional for cosmetics only, your right back in 88 my plastic L-88 scoop cracked on my stock hood, but it had been on 71-z since 79 and sat outside all the time,and probably had 100k hard miles, so im thinking the way this car will be treated the glass should hold up, im thinkin real serious about gluing it.

Try a local body shop supply for the glue, but you will need a specific gun to apply it. It is 2 part, like JB weld
