technics SP-25 armboard

I need to a adapt an Audioquest PT-5 tonearm to a Technics SP-25 turntable base. The round hole is pre-cut to 5 1/2" in diameter and 3/4" deep on the table base. I could buy the official, original armboard but it is designed especially for the EPA-500 tonearm assembly and would need to be adapted for the Audioquest arm. It might be cheaper to build one from scratch with all the correct measurements. Any suggestion will be appreciated.

Technics used the motor unit model number in identifying their dedicated plinths. From what I found on Vinyl Engine, there are four plinths for the SP-10 Mk2 --SH-10B, SH-10B3, SH-10B5, and SH-10B7. They differ in year of manufacturer, construction and mass.

The SP-15 motor unit had two plinth options -- SH-15B2 and SH-15B3.

Way back in 2006 I bought blank SP-15/25 armboards from Russell Collins:

It's worth an email to see if he's still around and can source them.

Hey guys...thanks for all your suggestions! I solved all my problems by throwing more money at it. I broke down and purchased a used Technics EPA-B500 arm base with an EPA-250 tonearm from an analogue specialist based in Hong Kong. This arm is an "S" shaped and features a removable headshell (great for cartridge changing). I was able to sell my Audioquest PT-5 on ebay for a nice profit helping defray the cost of the Technics arm. Listening as I type this and it sounds great. Nothing like the real thing!
