Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) Differences in Aero Screen Height

Hi all,

I'm getting ready to fit aero screens to my 1965 Plus 4 that has the aftermarket fold down windscreen.

I ordered a pair that were sourced from the UK (probably originated with Mr. Rutter - but can't confirm.) When I got them, I was completely impressed with the quality, the quality of the casting, the finish, the sand casting marks around the "Brooklands" marking, the fiber washers, everything was top notch!

HOWever...while getting ready to fit them, I noted that the glass seemed a tad short on my car compared to photos in the US of Morgan's with aero screens fitted. The glass hardly extended past my windscreen when I held them up to the car with the feet attached

After poking around a little, I found a set of slightly taller screens made by Tourist Trophy in the U.S. and sold by Moss Motors. These screens were a bit inferior to the UK versions, the casting was not as high quality, the "Brooklands" marking was shallower and didn't have the sand cast marks, and the washers were metal and not fiber. BUT, the glass was about 1/2" taller than the UK version. Photos below US version on the left, UK version on the right:



I'm leaning toward fitting the taller U.S. sourced screens. Will post photos once the feet are installed. May not be able to return the UK sourced screens as I did scratch the lolipops when I fixed the set screws during a test fitting. So you may see them for sale here on TM soon at a discount.

If anyone has any pics of a Plus 4 with the shorter UK screens fitted with a fold-down windscreen I would definitely appreciate it - as they are the higher quality piece and I'd prefer to fit them, but I just think the taller screens will probably look and perform better.

Best,

GC

Crowbar ... here's mine '75 with folding screen and Brooklands aeroscreens.

Thanks Image - they look great - and it seems you have the taller aero screens fitted - no?

Also - did you fit yours at the edge of the scuttle in line with the "lift-the-dot" studs - or farther forward?

On here somewhere from probably 2009 or so is a report on me fitting aeros to my 97 pls 4. They were the lower ones and worked fine.

I'll try to post pictures if I can find them Thursday.

One thing you need to be careful of is the wing nuts touching the windscreen when the windscreen is up.

Crowbar ... night-time here ... will take some pics and measurements of the aeroscreens tomorrow and post them here 👍

Ps ..... my car doesn't have the scuttle 'crash-pad' so your mounting position may be different ... good advice from John about checking with the windsreen up that the wingnuts don't clash.

Crowbar ... hopefully the sun is up round your side of the planet by now 🙂

Couple of pics of the aeroscreens .... no crash-padding on the scuttle of my car so your mounting may be a bit different ... I wanted them near the edge and well away from the screen ... mine are bolted through with little CSK stainless bolts ... most seem to use woodscrews into the ash frame under the scuttle which is closer to the windscreen.

I did find both the screens and the mirror moved about at speed on rougher roads so I welded up a little stainless bracket that stabilised the centre of the scuttle by bracing it to the dash (under the lip of the scuttle below the mirror) ... no more problem, solid as a rock.

I love driving about behind the aeroscreens even though it's considerably cooler here than with you!🙂 (but then, I've been a biker all my life) ... have the screen up right now as packing the car for a 650 mile trip with the Mrs so a little more comfort is in order ... the screens with the windshield folded flat looks the biz in my book!



The screens I have are 6.5 inches from the bottom of the frame to the top of the curve of the glass

Ps ... no doubt others can join in with details of how to mount then with screws and with the padding in place

Thanks Image - my taller screens are 6 1/4" and the shorter ones are 5 14/16th...yours are even taller than mine!



My car has the same scuttle as yours (no crash pad - just painted metal)…did you use sheet metal screws (pointed tip) or machine screws with a nut? I was originally going to use #8 machine screws with an acorn nut - but the more I think about it, sheet metal screws might provide more purchase if I add a small rectangular piece of metal underneath...would appreciate any advice from the group.

BTW - absolutely love the engine turned dash in your car - did you make it yourself? Very trick!

Best,

Crowbar ... I used little stainless set screws with acorn nuts.

The dash was part of the ground-up rebuild of the car .... I put a gallery/blog up here https://www.talkmorgan.com/ubbthreads.php/galleries/602934/keiths-4-4-resto#Post602934 .... bit rambling but the dash bit of the project is on there (when I get a chance I'll try to find which page to save you wading through the lot! 🙂 ... my philosophy is vars are for driving not concours so didn't go overboard with the cosmetics.

So I tried the stainless bolts and acorns...but sheet metal screws actually seems to have more purchase and be more secure. I cut little metal strips to sit under the scuttle that I drilled though and put the screws through, to provide more support I covered the pointy tips with small #6 acorn nuts held in place with RTV (a ridiculous bodge if I ever saw one!)

Came out pretty good - I'm happy with the results, also quite surprised by how effective the little screens are for wind mitigation. To counteract the slight curve of the dash laterally, I flipped the outboard lollipops on the screens so that the mounting posts were lower than the inboard lollipops. This effectively raises the outboard side of the screen just enough that the screens appear straight in relation to the windscreen.

What a lovely looking car Mr Crowbar.
