Thanks Bob. From my observations, it looks like just as you said, possibly an original that has come apart or was coming apart. The outer edge has more material than what i've seen before. The inner cut outs have been filled over with "chop" type fiberglass cloth much like the outer edges. The hood skin is of the "square" or "checker" type fiberglass. I have seen this cut out for the BB oval breather on one other frame[more a squared cut out than a arched cut out]. I'm just trying to track down vin numbers/dates to see if possibly they could have been made at the same time?? The shame of it all is trying to put it back to an original look. BTW, the hood has alot of high build primers on the underside surface. Chris
