For info, perhaps to help future queries:
Beta transverse links (fixed, pressed ones) measure approx 555mm between the bolt centres.
The bushes are 30.35mm outer diameter (metal sleeve outside) with the metal core having an internal diameter of 9.9mm
(Bush dimensions as measured by my Clarke's digital caliper, so subject to some small tolerance)
If someone can provide measurements from a Delta, that would tie up my query.
