I will have to be getting a larger scoop for my 81 here soon and have been looking at cowl style hoods. the glasstec hood seems to be a shorter cowl than the harwood , and the harwood seems to be a boxier looking cowl. Is this just the way the pics appear or am i right? Also which of the two are going to give me the best fit. Ill let you know that at this point i am leaning towards the harwood even though it is a pin on. I am looking for some comments from you who have seen these up close or have tried them out for fit , and what i should expect for fit.How are the pin on hoods to deal with.
