I don't have a picture of mine, but I used this as a reference.

I can get some measurements for you, one thing I did was to keep about 2 inches open at the base between the seats to allow some airflow. I also cut it and curved the top corners so I can up and down the convertable without taking it our (which takes 30 seconds)

Also bought a 6" red MG emblem from LBCARCO.com (6 bucks I think and stuck it to the windscreen) 1 inch from the top and dead center facing backwards, keeps the folks following wondering what the heck they are following.
 
Anyone have one on a Bugeye, wife says it is windy at 65.

What holds the thing on.
 
Got it and I see how they are fixed to the car. Looks like good stuff.
 
Anyone have dimensions on one of these? I'm getting ready to cut one out and I'm second guessing myself. I ended up with width overall of 40.5" (smaller at the base and top, similar in shape to what's sold) height is 13.5" but it'll sit down below deck level by 3", so 10" up. I've cut a board to run across the wheel humps and be bolted down to those bolts that stick up there, Lexan is an old display sign so has a bottom bent into it....
 
Just remember that if there is space below the lexan and the parcel shelf, you will get a rather strong draft through to the front of the car right at kidney height. I left a 2 inch space (maybe 3 ) below the lexan and the parcel shelf for some flow through. Not bad on a warm day but once the temps starts to go below 40 degrees it can be uncomfortable on a long drive. Sorry I forgot to post pics of mine. it is off the car right now so I will take some this evening. As I said in an earlier post, I basically copied the design here https://keith.miata.net/windblok.html I personally don't mind it being held on by a bungee cord. When I made mine I measured it to fit with the top up so I a can drive with it on all the time, top up or down, but not with the tonneau. I find that when I used the tonneau in the spring and fall it was nice in the car but my head was still cold, now with the windblocker on, I am warm head to toe. Jack is correct I have had pieces of paper on the passenger seat and they stayed there with the wind blocker on the car.
Oh one more thing, when I cut the lexan I used a dremel tool with a rotary saw blade. I finished the edges using a propane torch and "melted" the edges to makes them turn clear. They will be white and dull after the cutting. Be careful you don't burn the edge as it will turn black, bubble and then catch fire. Practice on the scrape cuttings.
 
Thanks for the info. I'm planning on a jigsaw with plywood blades (lots of teeth, little offset). I might hook the saw up to a reostat on my workbench so I can dial in the speed to keep it slow (keep heat down). I was hoping to sand the cut edge but "fire polish" worked for you eh? We'll see. I'm interested in how high yours is. The piece I have is limited in height but it looks like it will be at least as big as those sold. The Miata one is 17" tall, don't know how that equates with height relative to your head though.
 
I made one using 1/2 conduit shape sort of like a roll bar and it mounts in the top frame mountings holes its about 6" high,3/16 lexan. It just slips in and out no brackets no holes no nothing.Its not very pretty but man on long hauls its great the wife puts it in when she tools around town. $10.00 started out as a test to see if they do anything they most difenatly do! I'm not buying one this does the trick
 
Jack, Tim's Windblockers are held in place with a nut & bolt on each side...I've got them for my MGB's & love them....buy one - Kay will be happy!!
 
Yea, think I will do that for Christmas.
 
I just tried to cut mine. Not working out too good. I think this is one of those situations where it doesn't pay to be frugal. Tim sells something? Who's Tim? I tried a plywood blade in my jigsaw, tough going through 1/4", kept melting and getting stuck, crappy edge, then it caught and it broke (not the good part) but I gave it up for now. I'd have hours into cutting it and it'd look like crap so, well, suddenly $180 or so doesn't sound so bad.
 
Use a fine blade and cut with slow speed.
 
& on the LEXAN I cut for my racecar's windows, I turned the blade around bacwards.
 
You pulled rather than pushed??
 
lbcarco and morspeed one are the same then I guess, for the spridgets.
Yeah, cutting sucked, I tried different speeds but even with a reostat to control speed it would either not cut or it'd melt. Table saw with the right blade turned around maybe but I wanted some curved cuts. My Lexan is thick too.
The one's linked above look a little small, wonder how effective it is, I like the design.
 
one word....DREMEL

use a rotary saw blade...like butter and a hot knife
 
I think the difference was the thickness of the LEXAN I was cutting - mine was only 1/8".
 
When I made my windblocker (on my Bugeye)I used a small router with a straight veining bit at a slow rpm and got a clean cut. I made a pattern out of some 1/8" ply and used a guide collar on the router to follow the ply pattern to get a smooth cut. After you cut the plexi this way it will still have a roughish edge, so some light sanding will smooth that out, and then hit the edges of the plexi with the flame from your propane torch, just enough to begin to melt the edge and you will end up with a clear perfectly smooth edge. Keep the flame moving in a fan motion just caressing the edge so you don't completly melt the edge plus. You can do multiple light passes until it is right.
