    Following a forum post some time ago by Mike Woodley I have finally bought an MGF Windstop on fleabay to fit to my Cabrio (Hunter).

    Initial measurements on my LWB showed that the short brackets used by Mike would position the windstop too far back and foul the hood when it was down so after much measuring some alternative brackets were made up. These extend the windstop about 5” forward of the seat belt post and position the windstop just behind the headrests when the seat is fully back. (I had Marlin move the seat runners further back when I first bought the car so it was easier to get in and out). Once in I slide the seat forward about 2”. The passenger has a footrest of my own design so their seat can stay fully back to improve driver visibility.

    First trials with the windstop fitted gave less draught around the shoulders but a howling gale around the kidneys! Photo shows the gap between the bottom of the windstop and the hood bag “apron”. Mk2 mod was to put a 22mm tube across between the brackets and make two triangular brackets so the hood bag could pass over the tube and be trapped by the hood bag. Result NO gap and a really comfortable warm cockpit! By using two rubber tap washers between the windstop and the brackets the windstop can be easily moved flat for improved visibility when reversing. The hood can also be put up with the windstop in the fully “up” position.

    Although the seat belt passes under the whole assembly even when the seat belt is over my shoulder the belt does somehow get above the bracket in use. Probably due to reaching up and over to pull the seat belt when fitting. Further work in progress to make a smooth guide “loop” for the seat belts which will be attached to the front bolts. Attached photos show work to date. Peter.

    Hi,
    I also have fitted this MG wind defector and it works quite well apart from being draughty towards the bottom of the seat.
    Is it possible for you to post detailed measurements of the parts so we also can benefit from a draught free cockpit
    Thanks
    Stewart

    I may have some sketches somewhere but meantime you should be able to scale off the middle photo above which is on my LWB Hunter. Also seat type and backrest position will dictate how well it will fit, so my dimensions would not neccessarily fit another Hunter / Cabrio, even if LWB.

    Since the above photos I have recently turned the triangular brackets around and added a further link and thumb nuts each side. That mod allows me to move the windstop about 2" further forward and 1" lower so when being lowered it will clear the hood when it is up and also not foul the top of the seat backrest. The windstop then lays flat on top of the rear body trim and the hood can also be folded down flat on top of it if required.
    Working out the geometry of the fixings and raising and lowering movement is very much a trial and error process which I solved by making a 2-dimensional mock up using a porridge carton (more rigid than a pizza box!) and a couple of eyelets. I also added a popper to each side of the hood bag so the ears are held together underneath the seat belt to close off the side gaps. Peter.

    Hi Pete, how did you thread the ends of the 22mm tube supporting the hood bag apron? This is something I intend to do with my wind deflector, as I too have the same gapping between the deflector and hood bag. Regards Mike Woodley.

    Hi Mike. I used the concept aluminium from B&Q. They do a range of plastic fittings that fit inside and those have a M6 thread in them. Peter.

    Hi Peter, Thanks for that, picked up some inserts today, just need to find some time to make up a couple of brackets and fit to car. Thanks again. Regards Mike.

    No Probs Mike. BTW I put a strip of self adhesive foam on the top of the fixed tube so the windstop squeezes the hood bag down on to it to avoid slipping. Also I used flat rubber tap washers between the bits of the brackets that the knurled thumb screw clamp together, to provide some friction. That way I can reach over the passenger seat rest and fold the windstop down for better visibility when reversing. Peter.
