Default Re: brake booster for a '65

I am doing that exact upgrade and GMC mounting to the fire wall is different than the ones they sell for chevrolet. The GMC has 3 countersunk fasteners where as the chevrolet they have 2 existing bolt holes and you have to drill 2 more. My question is do they make an adaptor bracket with the 3 countersunk holes
