Vintage Japanese Turntables

My LPs have been in storage for many years, but I am thinking about getting them out of storage, buying one of the direct drive turntables I loved in my youth, and using a still new and in the box SME III tonearm I have in my collection.

A couple of questions for the analog experts, please

1) If I find a turntable without an SME armboard, would it be difficult or expensive to buy an SME armboard, or to otherwise adapt say, a Grace armboard for my SME arm? Or adapt the turntable?

2) I have found the Denon 103 debate interesting because I remember this as a cult cartridge which I thought might work well with this arm?

3) Any other concerns for vintage Japanese direct drive turntables?

I understand my choices might be largely sentimental here and easily outpeformed by other things - but for this application, I just want good to very good sound and vintage cool, more than state of the art performance.

Thank you.
