Good fiberglass shop in South eastern Ma.

[Solafide]

I recently laid out plenty of cash for an Armstrong double wide bracket with a swim platform only to find out that my origanally sterndrive transom in slightly bowed outward and the bracket will not lay flat against it.The transom is very thick and rock solid,does any one know of a shop in south eastern Ma. that could make a modification to make this work? Thankyou
