Try A Brooklands Aeroscreen

With the inclusion of a steering wheel cowl, use of the JZR windscreen is not possible.  I have to confess, upon inspection, I was not very happy with its look anyway.  I wanted one of those aeroscreens I saw on some of the other JZRs - that was the look for me.  In the US, Moss Motors is a supplier of Brooklands Aeroscreens.  But, when I called to order, they were out of stock.  So after a little web surfing I found Vintage Supplies in the UK.  Vintage actually had a sale on them and I got mine for just a few dollars more than Moss wanted - including the shipping from the UK!

The picture above shows the basic anatomy of the Brooklands aeroscreen.  One key feature of aeroscreens is that they are generally made with safety glass and not lexan as the JZR windscreen calls for.  The safety glass is glued into the aeroscreen's frame in a similar manner to the way a standard car windshield is affixed into its frame.  The angular alignment of the aeroscreen's banjo and foot allow it to be mounted on both flat and curved surfaced.

However, in my build the curvature of the steering wheel cowl is too great to allow the aeroscreen to mount as I wanted it.  See, I wanted the aeroscreen to mount parallel to the ground; I noted that almost all the JZR's I saw with aeroscreens had them mounted at slight angles. So, given these two little issues it was clear that I needed to come up with a different way of mounting the aeroscreen.

After a bit of brainstorming I decided to discard the aeroscreen's feet and fabricate a set of simple mounting posts, as shown in the drawings below:

The results seem to look very good and allows for simple mounting as shown in the pictures below:

The next picture is a close-up of the driver's side post.  Note the grommet at the base of the post, its a simple faucet gasket i got at the hardware store.

And an overall frontal view to get the real feel of it:

If your wondering how I aligned the assembly? It was simple, first I scribed a line on the  steering wheel cowl that was about 1 inch in from the rear edge  of the cowl  Then, with the new posts loosely attached to the aeroscreen, I used a small 6 inch level placed on the bottom edge of the aeroscreen's frame.  When the assembly was in a level position, my brother Ed market the post location  as they sat centered to the scribed line on the steering wheel cowl.  Pretty simple, but it takes two people.

I have decided to just use one aeroscreen for my vehicle, but a lot of folks use two.  Obviously, by varying the lengths of the mounting posts used, you can just about mount an aeroscreen anywhere and in any position - well, practically.

One final note on this, if you do decide to go this way, even if you don't have the posts made from stainless, steel, I would strongly recommend using stainless steel bolts and set screws to allow best exterior service life.
