How do you measure that Tony?

It's an 8 mm thread and the length of the "tube" part of the bolt appears to be 3 x the dia. of the thread. So 24mm which is 15/16" the large washer is probably not quite that thick?

We put these on ours when he first brought out this version of lifter and Sarah and I think it makes the driving position more comfortable.I did test with the home made version first just to see if I like it.I have one set I can send you to try if you like ?
Anybody have thoughts on ARBs, H&R upgrade or polybush the originals?

Nice looking strut brace you have there ash! Next week I should have the front strut braces ready for sale (6 cylinder only) they will be in a choice of red, blue, black and silver. They will be twin steel tubes for extra rigidity and low weight with a twin bolt mount. Fully welded for extra strength.

I designed that for Barry, looks good in the flesh@t-tony
This is a pic of the kit
The recess on the spacer positions itself underneath the front of the seat rail and 'locks' into place. The long nuts then bite onto the thread through the seat rail and spacer. You have to loosen the rear bolts just to allow the angle to change slightly before tightening them again.
Took less than 10 minutes including some photos

Yes I've seen the Barry kit and it does look very nice, but that's not to say there isn't a more cost effective alternative.

ps. A very similar one to my idea is available for sale in the US

The reason it is designed how it is Tony is do it locks the joint in place, once tightened up it cannot move, unlike the tube nut version which will collapse under an impact load.
Safety first!

I don't see how it can collapse Rich. To collapse it would have to move forwards, or backwards,(which it wouldn't) it can't move forwards because it is locked position by the much larger rear mounting bolts. Also lifting it creates a triangle between the front and rear mounting points, which as most know is the strongest shape in engineering.

We all love triangles.
I did yours Tony to see if I liked it and it was great ,I feel Barry's kit is a little more robust ,wether it needs to be,I don't know and you do get more of a rake your way.

I'm not knocking anyone's design or education, but all I can say is the Barry version mirrors the original seat application which has been crash tested, therefore there is a good chance it will stand up in a crash. The other tube nut version would perform different just by nature of design.
In the seat application it is the front bolts and rail dimples that are locking the seat in place, the rear bolts are larger because they need to exert a higher clamping load to resist joint slip, the front cannot slip if in original configuration, but it could with the tube nut version as you will not achieve the clamp load with the diameter bolt used.

If you've got these fitted in yours Tony I'd like to have a sit and see how they feel. Do you have the standard seats in yours? If so I'll try them when we pop over. 
I personally love the idea of my seat tilted slightly, when I was working with Dino's car it felt really comfortable. But.....
1) the front studs will be under and increased tensile load because you have moved the load point.
2) when you tilt the front up the rear bolts wont sit flat so you don't get the whole head in contact with the seat rail, again exerting unstable load on the bolt.
But with stresses and strains we are talking in huge loads which would only be seen in a accident.
Looking at both kits with an engineers eye Tony' kit would be the stronger of the two (because the load is spread)but both are functional for what we need them for.
Sorry guys that's my two pence worth.........the plot thickens

I would think that would be more likely to interfere with the motor operation?
