Re: "Ride Height" - 77 MGB
Apparently the "ride and handling" kits that are readily available help the later, rubber bumpered Bs handle more like the earlier chrome bumpered jobs. Stiffer shock settings and, I think, very slightly upgraded springs. The original reason for the raised ride height was for Federally mandated bumper and headlight heights....make sure that your state doesn't check these sorts of things.
