Thanks guys. Can't wait to put it on the ground but I want to finish the nose first.

 Here is another detail shot of the sway bar setup. Scored these arms and sway bar at a nascar auction years ago. They ended up working perfectly.



Will that a-arm stand the bending stress of putting the pick up point in the middle of the tube? Looks nice!

. Thought about adding a rib to the arm over the sway bar pickup but the tubing is 1.5" x 1/4" wall dom. May still do that though. Thanks

Got the windows in last week from Shields. We went with 3/16" tinted for the back and sides and 1/4" clear for the front. All of it is hard coated for scratch resistance. I got the rear window done for the most part. I am not too happy with the way the allens and washers get along. The washers are actually meant for 100* heads and the allens I have are 82*. They aren't bad but I will be happier when they sit more flush.

See what your talking about on the Countersink fit. I'd fix that if possible. Overall beautiful build.

I want allen bolts but can't find any that fit these washers. I may just make a little die set to reform these washers. Probably won't take but a few minutes on the lathe then sit there with a hammer resetting the angle on the washers... The things we do for race cars  rolleyes                  cheers

That's probably going to be the quickest and best route to take. At least then you can get bolts anywhere off the shelf.

There are some cases where we use Phillips drives instead of Allan's on small sizes because they don't strip out as easy.

Aerospace stuff has almost all 100 degree countersunk heads-- bolts, screws & rivets. The screws are usually 10-32 and most bolts are also fine thread. Try eBay- you may find what you are looking for there.

Neil is correct, those are 100 degree heads on those bolts. Aircraft Spruce has them and the washers. They are 10-32 as well...

We used more than a couple on our car. We also sell a tool that countersinks the profile for those washers so they can be flush mounted.

We went with 316 SS allens for the better corrosion resistance.   The bolts in the front windshield pretty much reset the angle in the washer by themselves as they bolt down tighter against the solid rubber under the glass. The rears are compressing dense foam that spaces the window up flush with the hatch so they didn't "self correct" if you will. I will fix that.  The front windshield frame is perfect for bolting straight into it. I used knurled steel rivnuts. Turned out great!






Daryl I have noticed from time to time that the pics don't show up. Not sure why
