Are you just trying to replace the block, or the whole swivel assembly? If the former, is your base a Harken?
And, to confirm, you have your mainsheet rigged aft boom with a single part coming down from the boom to the swivel? So you'd need a single block.
A 50 +/- mm size block with swivel connector sounds about right, although, technically, if the base already swivels, the block would seemingly not need that capability as well.
But a swivel connector usually has a bin rather than just an eye and perhaps that's the key to connect it to the swivel base.
