I have a '62 SG that been in pieces since the early 70's. I have the original sideways Vibrola but it's missing the arm assembly and cover .What years did Gibson put the Maestro Lyra on their SG's? Is it better to just put the old Vibrola on for historical purposes and hope I'm able to find the missing parts and cover at some future date or change over to a Lyra or even a Bixby.
