Hi guys. I'm wanting to upgrade the rear caliper on my 86 FXWG which I've owned for the past 26 years. Currently running twin four spot Perfomance Machine Calipers & discs on the front & a twin piston Lockheed on the rear. I've been checking out all sorts of calipers from. billet four piston DNA, Ultima, Revtech, Late Harley to Nissin, Tokico & Brembo. Also looked at Jaybrake & PM, but they want the earth for them. Have seen a pic of a six spot, Tokico conversion which interested me. It just so happens that I managed to pick up a six spot  Tokico caliper today at the right price. Has anyone done this conversion or one similar and has a template for the bracket. Cheers, Swampy.
