Try this: https://cgi.ebay.com/ebaymotors/Wind-Bloc...=item1c1598f68e
It's a well-made product, installs fairly easily, and works very well.

I don't have one for the Sprite (or the MGBGT 
), but I do have one form my BMW convertible. I've gotta say that for anyone who drives their convertible on the freeway or for long distances regularly, a windblocker is the absolute best accessory you will ever buy, if only for the fact that your ladyfriends (or guyfriends if you swing that way) will once more agree to go for a ride with you because their hair won't get mussed up with the top down.

By "windbreaker," I am talking about the plastic shield that you install behind the two seats that reduces wind turbulence in the cockpit.
This device appeared early after the Miata appeared; it was one of the first after-market items for the Miata. The down side: IT ONLY WORKS EFFECTIVELY WITH THE WINDOWS ROLLED UP !!
I was at a Car Show last weekend sponsored by a company that sells these windbreakers. I asked one of the company owners if this is still the case. He said "yes." Miata Magazine would report that the shield was about 25% effective with the windows down, and about 90% effective with the windows up. I passed on the shield, as I cannot bear to drive a convertible with the top down and the windows up or sidecurtains on.
FWIW, I hope this helps.

I'm not sure you're right about that. The windbreakers in both of the BMW convertibles I've owned and in a Miata I've ridden in have all worked beautifully, windows up or down. Granted that the amount of wind is reduced the most by having the windows up but they work fine with windows down. The reason the windbreaker works is that as air passes over the top of the windshield it is compressed and speeds up, then is sucked back into the low pressure region behind the windshield (i.e. where you sit) resulting in a backdraft and buffeting. Here's an illustration of how a windbreaker/windblocker blocks the backdraft...

I agree...but it might depend on what one considers "effective" and the design of the product.
The stock wind-blocker on my Miata is only a few inches high. It helps a tiny bit with the windows down but helps a lot with the windows up (neither way is dramatic though).
I removed the stock windblocker when I put my new top on the car, so this fall I started using a Cobalt/Oris mesh windblocker. It looks to be similar in size and shape to that ebay one for the MG. With the windows down it stops a <span style="font-style: italic">lot</span> of the wind-tunnel effect on the back of my head. With the windows up it's close to only have a big sunroof on a sedan.
Some people might be disappointed if they think a windblocker is going to completely remove all the excess wind, but the difference between with and without is pretty remarkable.
