I notice the seat belt (harness) mounting eyebolts are horizontali.e aligned with the harness shoulder straps. I believe the MSA Blue Book shows they should be at 90deg to the direction of force applied by the harness. In your case with enough force the eyebolt would pull out of the cage. It will fail scrutineering. I would have it checked by a friendly local scrutineer (check out any local Motor Club) before going to your first event.

Harness mounts regs changed to require 2 at shoulders rather than 1.
I don't think that regs state that the bolt should be at 90 degrees to the force and if they do then they must have been written by someone with absolutely no brain!!!
A threaded fastner and a rod is strongest in compression and tension, not in shear...The pull force of a thread is measured in many tons of force..The shear force in real terms will be much less.

I will the old pic of me in about 1985 or so I was about 22-23 and feeling pretty happy/smug that I now owned a car that could run with a cobra... (nevermind the work to get it finished..) But Sonic, the rest is spot on..
Now that I think about it, this is probably the best place to update the "history" as such of this car from probably the farthest back owner---ME! :P
Anyway, I had moved to San Diego from Colorado and knew a little about TVR's as I owned an old MGA as my first car, but once in California I had mentioned to friends in Colorado I had seen a Griffith at an Autotest out here and MAN was it fast! Several months later one of my friends in Colorado told me about basket case Griffith for sale and was I interested?? I'll try to shorten the pre- and post story of that time, but I was told a tree had grown up in front of the car and it had been offered at a bit of a steep price with no takers. The house wreckers had appeared and a buyer was offered a fire sale price If they came and got it NOW! From that time until I bought it and picked it up in Colorado was about another year and a half. The pic shows the car sitting so high as some loon had stuck a straight live axle in the back and it came sans drivetrain. Over the next 10-15 years, I acquired a new chassis from DG, a few suspension bits and a 5 bolt standard bore hipo 289 with some special original GT40 heads. ALSO in the meantime I had started to SCCA autocross(autotest?) a 79 3000S and taken 2nd at Nationals and decided if I was campaigning the Griff it would have a 4.5" shorter wheelbase and double the power! At that point I decided a LWB Tuscan would be a better car, so I set out looking for one and found a 68 V8 Tuscan SE. Once I had that I decided I should let the Griff go.
I sold on the car with the motor and parts I had acquired , but I kept the special heads and intake. It went to anther friend/TVR nut (Irv) in Virginia, USA. It was there that it was "closer" to its parents/creators/early caretakers and the owner found gents that worked for/with Jack Griffith and they said it was one of the 3 original "lightweight" test mules. I don't believe it was the 3rd car after the prototype, but they did tell the new owner that they kept it about and added or changed things to see if it worked better or worse, both in safety and drive-ability. As for the lightweight bit, it made perfect sense but had never dawned on me. Over the years I had seen a few Griffs in various stages of completion and I had forgot that I could never push on mine as the fiberglass was extremely flimsy, yet others seemed more substantial. From what I understand this was a hallmark of a lightweight...less/thinner fiberglass. The Virginia guy got a few more bits and then had to abandon the project and sold it on to Fabian? in France.
I actually don't know much of what happened to the car in France at all, I'll defer to Jon on that one.
I actually bought back the motor from Irv and still have it... but it was stored with the heads off in Virginia and had some rust in the bores that may not allow it to be a standard bore anymore..
But I'm still debating whether to put it in my Tuscan or not as the Tuscan is supposed to be the first 302 powered car... but thats another story..
Overall, I would love to sit/ride/drive the car again someday!!
I guess as I find old pics of the Griffith I should post here.
