Sorry if this has been asked before. I have finally tracked down a pair of mx5 seats I want to install in my 77 moke. I was only recently thinking of seat belts once they are in stalled. I assume that I will require inertia seatbelts? My rollbar/seatbelt mount does not have a reel mounting plate, so I was thinking of using the existing mount on the floor to attach the reel and the other end of the belt. It would keep the reel out of sight. Anyone every mounted them like this? Or are the lap straps fine for the mx 5 seats?
