when i got my arrow belt drive they wanted 60.00 dollars for the adapter and i said no way. i bought a 1" thick by 5" wide round piece of aluminum for 12.75 dollars. took the top pulley and sat it on the 5" piece of aluminum and aligned it to the pulley and drilled the holes through the plate using the pulley holes for the template. i took my face plate and aligned the rotax bolt pattern with the pulley and drilled the pattern. the face plate had both the arrow belt drive pattern and the rotax pattern. so just bolted the plate to the faceplate and drilled the remaining rotax pattern. didn't have any fancy equipment to align everything up perfect so i enlarged the arrow pattern holes 1 drill bit size to let me fine tune it when assembled. works as good as a 60.00 dollar adapter and less money.
