I purchased one of these hoods for my cutlass and was very happy with it. Mine uses standard car hinges and the lock down style pins. I actually bought the hood on ebay from a seller by the name of TAMRAZ and here is alink to one of his hoods just like I bought
http://cgi.ebay.com/ebaymotors/1971-...QQcmdZViewItem there are a few more sellers of these hoods on ebay like the parts place just do a search in classic car parts in ebay motors and type in cutlass hood in the search field. The hood I have was actually manufactured by Fibertech and ia all fiberglass "no steel frame" but if you have a 1970 cutlass there are aftermarket hoods that have fiberglass over steel and tamraz sells them as well as the lockdown pins. This guy has it all and his prices are pretty good. I did a lot of shopping before I found him on ebay and no I don't work for him, I just found he had a lot of stuff I needed.
Hope this helps
