Brake pads for DiamondBack Ascent 1990

[Mulemad]

My DB which I've owned for 30.5 years needs new brake pads. It's still on its second set which date from god knows when...20 years ago? They are cantilever of course, Shimano model BR M351. I have found some originals online at sjscycles uk (or someting but as I live in Portugal Brexit has made a nightmare of shipping stuff to over here, and the total price becomes treble. Are there any other more modern ones etc that are compatible and easier to access in europe? I don't want to change to another system as the bike is in good nick and has all its original parts bar perishables such as tyres and grips.
Any suggestions greatly appreciated.
