I bought one of their bolt on fiberglass hoods for my 77 about 10 years ago..... it didnt fit worth a crap. No matter what I did (short of cutting a big piece off), the back edge prevented me from having the windshied wipers on. When I took them off, the hood fit, but the pivot sprocket was right up against the hood. To get it to fit, I would have had to do some major modification. This was not a "little trimming" modification.
I sent it back and they charged my a restocking fee of like 15%. I pitched a fit since it was their crappy products fault, not me changing my mind etc. and finally had to take them to court. I won, but never saw a dime.
Granted this was like 10 years ago, but I will never order from them ever again.
Go with the Harwood.... much better company in my opinion.
