I have been grappling with a similar situation with the sidescreens on my Roadster, which has a different rubber seal (see photo) for the sidescreen-to-screen-pillar junction, as used on later trads. So apologies if this looks like thread drift, but I hope the following contributes to the general body of knowledge on sidescreens.

I commented in a previous post that "...I couldn't belive that the original factory fit of the sidescreen had been so (apparently) slapdash". I did attempt to bend the mounting brackets as advised by other TM'ers, but even with a sturdy vice and a BIG hammer, I could not get the 3mm alloy to change the angle of its bends.

Part of the problem with my sidescreens was that some aftermarket sponge rubber moulding which had apparently been added to reduce "cold elbow syndrome" was simply forcing the sidescreens into a rather unnnatural position. Well guess what, having removed everything so that I'm back to just the powder-coated virgin windscreen frame, the fit is uniform top-to-bottom and sideways. I have now changed my perception to "I can't belive how well the factory got the sidecreens to fit". (And importantly, for anyone else tackling this, the internal angle in the windscreen frame is NOT a right-angle).

Frankly the biggest issue I had was getting the adhesive residue off the inner face of the sidescreens where the add-on sealing strips had been fitted. Mohair doesn't like being detached from Evo-Stik / epoxy / superglue. I invested several hours' work near an open window with loads of cotton buds and a variety of fairly noxious substances including Evo-Stik solvent, Loctite glue remover, denatured alcohol, cellulose dope thinner, and acetone, and all but a small area of staining has now gone.

The seals are going back in tomorrow (if the storms don't blow down my garage !) As a failsafe, I have invested in some strips of 1mm, 2mm, and 3mm sheet rubber to act as "packing" just in case.
