Question for users of Devere 504 and Ilford MG 500

After years of using these two together, I finally got the correct Ilford adapter. The only things I'm missing are the two weights (rectangular and bar) which attach to the adapter. I could fabricate these myself, but I could use some dimensions. Would anyone mind measuring theirs? I need the overall dimensions and hole locations if possible.

Also, can anyone recommend a supplier for Devere 504 parts? I need one of the locking knobs for the focus/height wheels. I'm located in Portugal so I'm probably looking at mail order, preferably Europe. Thanks!

Odyssey bought De Vere and they can sell you the parts you need. Here is the link. They are in England

I have also purchased parts and a manual or two from KHB Photographix:
