Okay, so installing the front hub adapters was not as easy as on the rear. The problem is the Trigo pin drive adapters will not fit over the Wilwood hub. As you can see in these pictures the adapter won't seat flush:
The solution is to turn down the Wilwood hub grease cap on a lathe. Well, I don't have a lathe. But I have a friend that has a lathe, and a shop-full of many many, more cool tools. Rick Bickle to the rescue! And his shop is only 8 miles from my house. Rick has been such a huge help on my build, and I can't thank him enough. Rick is a Texas Cobra Club member, and owner of a really nice Lone Star Classics cobra on which he has done a lot of innovative custom work.
Next step is to once again cut the lug bolts down to the prescribed length to accept the Trigo adapter pins. Now the lug bolts have been shortened and the hub grease cap turned down. The adapter now fits.
Next is the tire mounting:
So, I didn't want to take my REALLY expensive tires and wheels to just any tire shop for mounting, that had never seen a knock-off hub wheel. So I asked around the north Texas cobra community for recommendations, and ended up going to Texas Track Works in Ft Worth. I was very pleased with their service, and the cost was very reasonable.
 They installed the tires while I waited, were gentle with the wheels, and because they service a lot of SCCA track cars they knew how to mount the tires, which proved to be not so simple.  Because of the "balloon-ey" (is that a word?) nature of the Goodyear BB bias ply side walls, they used a portable tank of compressed air to "blow out" the sidewalls to get the bead to seat.
My tires are now home in my garage, cleaned up and mounted on the cobra! For the first time it's rolling on its own treads, and I can get rid of the cheap-o homemade Harbor Freight chassis dolly.
