i don't know about that. i have heard very good things about the AMD stuff. i have read that guys with one NOS quarter and one amd quarter had to do less work with the amd one to get it to fit properly then it took to get the NOS one to fit properly. weather it factory original, NOS or AMD it will need work to fit the correct way. just the way it is.
but back to the hood ad here. looks to be a decent hood. a and a good price depending whats under those primer spots..
