55 mm lens board for a Durst L-1200

I plan to adquire a Schneider APO-Componon HM 150, that, I think, it has a 55mm mount diametrer.
The problem (apart from the expensive price) is that I don't find any lensboard with that 55mm hole. My enlarger is a Durst Laborator 1200.
The lensboards for this enlarges are called LAPLA and I've seen them from 39mm to 50mm but not 55mm.
Any of you can help-me?
Thanks for your time

Can you get a blank board and have it bored? Or get the 39mm and have the hole enlarged.
