I had what appears to be a stock hood with aftermarket hinges that gave me the same problem. I ended up elongating the mount holes on the hinges so that they sat in the proper position to bring the hood down. I don't know whether the after market hinges just don't work on the older trucks, (Some things changed at around 1976 and there are a lot of parts that are separate for 1973 - 1976 and then 1976 to about 1980 and then again from about 80 to 87. I suspect the after market hinges would work on newer trucks but not 73 thru 76. I have not seen an original hinge for a 1974 so I don't know that for sure. Hoping maybe there is an expert out there who knows about this and maybe knows where to get the proper hinges. If you know of any source for a hinge that will work on a 1974 please sing out!
Thanks for your reply,
