Jason Shulenberger Jan 2nd, 02, 1:13 PM How can I spot if a Cowl Induction hood is an original GM hood, or a reproduction? Are there any identifying numbers stamped on the originals that are not on any of the repro's? Jason Shulenberger Jan 4th, 02, 1:16 PM No takers on this? There has to be a way to tell them apart. I heard something about the bolts for the flapper door are molded into the OEM hood, but not on the aftermarket. Any information is appreciated. 70isfine Jan 4th, 02, 8:47 PM Usually you can spot an aftermarket panel by the crummy fit,but the Goodmark hoods are almost perfect so its hard to tell. FO_FDYFO Jan 5th, 02, 2:35 PM easy. gm has nut welded under where the flapper door bolts to. repro just have holes. so if it has threads its gm. I have seen this several time but I guess someone could make them with weld nuts in them. ------------------ 1970 Chevelle 454 Wagons haul A$$ in style!

Who was the manufacturer of your hoods? DZAUTO Jan 6th, 02, 7:51 AM I don't have any idea who the mfg was. You can call OPG and see if they have that info. ------------------ Tom Parsons FO_FDYFO Jan 7th, 02, 5:47 AM I don't know either. I bought it used. and I have seen more then one at different places with out the weld nuts. if they are not there it is a dead give away. and I guess what I am hearing too is if it does have them it still does not mean it is gm. so I guess you don't have your answer yet. if it has the weld nuts then I don't know how to tell if it is gm or not.
