Dear @rich121 :I know that you are exited by the plinth you found out and that be there with the seller that's anew item.
Now, yout MK3 always was sold aalong the EPA 100MK2 and for very good reasons between other is IMHO the best pivoted tonearm ever.
In those times the SP10 always had mounted Technics tonearms never a FR or almost no any other tonearm.
As I toldyou that the more important and critical analog aitem for any cartridge is the tonearm before any TT. The relationship/matching between cartridge/tonearm is always first than all to achieve the best quality performance during play, nomatter what.
Here and EPA 100 on sale:
Here a EPA 100MK2 ( very rare ) that was sold same day that was offered. The 100MK2is the only tonearm everwhere the arm wand/headshell were build with Boron, yes the same cartridge material cantilever used in the best today top cartridges.Go figure ! ! ¡¡ Sold in a true bargain price even that that headshell is not the original for a MK2:

The next is similar toyour 500 maybe with different arm wand ( excelent tonearm too )
Here with the arm wand I recomended before:
All those Technics offered separates counterweigth for heavy cartridges.
If I was youI wil try to find out both of the EPA 100 or al least one of them.Your plith will be there don't worry about.
Anyway it's only an opinion trying to help some one like you.
