Had a helpful exchange with Brian Gateson @ Techniques. Seems he has one of his own bars in his +4 easyfit car and it fits....

.....although the catch is you have to remove the stays that run forward from hood hoop to the windscreen toprail.

Thinking about that, will the hood then billow out at speed? My old 4 seater had poppers on the top of the sidescreen frame to which the hood fixed. Easyfits pop to those stays.

Waiting to take a look at it myself and hoping to get some pictures. Again, please let me know if you have already seen one of these in place.

cheers, Colin
