Which arms share the Rega Geometry?

AudioMods , Moth and Mitchell tonearms have the 222mm pivot to spindle length

I took the arm mounting plate for my VPI Aries into a good plastics supply house/fabrication shop, and had them make a new one to the stock one's exact specs. Parts (1"  thick acrylic) and labour, under fifty bucks.

Take the advice of @vair68robert and look into the Audiomods Series 6 arm.

@dhcod What kind of turntable do you have?

I think some of the funk firm arms

I’m looking for an easy drop in temporary solution while my new table is being built. Then when I sell the table, the arm goes with it.
