Hi all ... Can anyone help I am building a Locost (Highcost really) McSorley +442 Problem is is getting aero screen, size is bigger I Have the scuttle ... also the rear panel in GRP and bonnet in GRP or any panel ... can anyone help ... Mike ...

I'll probably get slated for this, but the GTS W7DE is based upon a McSorley +442 plan, so may be worth following it up with them for price/availability of parts?

I used two individual Caterham aeroscreens on my build, as they're sided and fot the scuttle quite nicely. I spent a month or two hunting around for an aeroscreen for my W7DE, and no luck - only other option is either a windscreen, or custome made aero jobbie home-made using acrylic/perspex as some on here have done.

Triton is one to get a hold of. He can point you in the right direction re. Haynes, which I believe is basically McSorley size. Also, go on the Haynes Roadster forum.

Rear panel. Making one isn't that difficult (not super easy, but if I can do it...). Ditto Bonnet. If you cannot find +442 wide parts in GRP, you can widen book width ones. Search "widen arches" on here to find out how.

Is the McSorley +442 wider than say, a MK?

yes, MK is 42 (which is book width) C'ham Series 3 is 39, and McSorley is 4" wider than book, so 46" wide.
