You 'might' be able to use/bastardise the adv tobinators if you have them, I can't honestly remember - have a look at the pics of them.
You can try the MRA without tobinators, tall sods like me need them (6'3").
Motobiker - normally the MRA cures it, but using tobinators gives you a whole new range of adjustment. I found the std MRA was
okay, but the tobinators cured it completely
You could always ask if anyone's near & got the std screen fittings and see if they'll loan them for a ride - takes 5 minutes to fit & you'll know straight away. I'd loan you mine, but I'm a bit far away
