CRASH69, What I mean by discontinued is - Discontinued from any GM dealer, I am sure all the parts houses will allways have the reproduction hoods- EG.=Goodmark, Dynacorn etc. Not sure about the GM hood, unless the parts dealers have a stock of GM hoods. I kinda doubt that GM would sell there stamp presses, but who knows. GM actually stopped making ZL2 cowl hoods for a while back in the late 70,s to early 80,s, but the demand must have been huge as they retooled and made them again. By the way when I first bought a GM cowl Hood back in the mid 70,s they were like around $100 wholesale price in Canada, guess I should have bought a truck load considering the current GM price of $900+.
James, The notch I am refering to is on the back on the outside vertical lip, do a search under GM cowl Hoods, This had been discussed before.
I tried to post a link, but couldn,t get it to work. Do a search under user post by- SixtyAte, he posted pictures of repo and original GM.
Hope this Helps. Mike.
