Belt info;as used on our 2B+ -- Securon Pn 264 automatic rear seat belt,3 point mounting. The auto reel can be mounted in any position,you then set the fore & aft -- up & down dials so that the reel operates correctly. I mounted the reels in the space between outer panel & inside face of chassis (we have not fitted inner panels) on a 4mm S/Steel extension bracket which in turn is bolted to chassis plate carrying Ford suspension cross-tube. The top fixing is a shaped steelplate approx 120mm x 40mm with a 7/16" unf nut welded to back; make 12mm hole in vertical of roll-over tube at correct height, slide bracket up inside roll-tube (on end of plastic pipe) & secure in place with 7/16" set-screw. I drilled & tapped right through roll-tube & belt bracket above & below seat-belt mount (5 or 6mm) loosen set-screw to open out holes for clearance,re-assemble & fit belt mount. (File a small radius for good fit to roll-tube) I used the seat back belt fixings for ends of both belts. The only thing I wish was a little better would be to have a stalk mounted clip instead of the webbing one supplied. End of story,hope that helps.
