My second hand sprinter did not have a front passenger seat and I am looking to fit one. The seat belt mounts were boxed in behind the ducting and wiring for the ceiling mount /ac unit. I can construct a space for the seat belt to run, but having removed the ducting box I've found the old belt has been cut. The mounting points are all still there, but I will need to replace the belt. The reel has a silvery metal rod coming out of the top which is a good 6" long or so - no idea what this rod is and none of the belts I can see online include it. Does anyone know the part number for the reel and belt - and is this rod something I can just take off the original or is it part of the reel?
