I "think" TFTuned is where you need to be. I was, rather bizarrely, measuring for just this last night. Emailed BETD weeks ago and got no response.I am trying to find a bush that would fit a vintage Rock Shox Deluxe (Yr 1999/2000 era) to a BETD link for a Specialized FSR 99.
The BETD bolt is a 8mm and the width across the BETD link is 50mm.
The Rock Shox Deluxe has an eyelet diameter of 12mm but has a polymer bush insert that reduces that to 10mm - so not sure what diameter to go for? A 10mm diameter with a 8mm bolt seems too thin and prone to bend? But a 12mm axle would be metal against metal.
I did find a photo of one fitted online so there must be a bush out there that fits?
Plus the BETD guys said this link was designed to take the shock FSR shock yet they have no mounts now…
