The ULTIMATE how-to on Kafer Cup DIY

[super vw]

Ok, i have been thinking about this topic all day now
I have a local source for some "FK" rod ends (Clevis style) or normal ball joint rodends.
I have some more questions on this.

- What size and length upper shock bolt will i need, it seams like i need about 1 1/2 inch of material to mount the tabs on a spacer on the shock bolt, or is more needed?
It also looks like i would need to cut some of the body where the access hole is for the upper shock bolt, no problem there.

So what thickness do i need to make the tabs out of (would 1/8 be ok? or should i go 3/16. Also what thickness and dimentions would be best for the sleeve/spacer that you weld the tabs on that also slides over the upper shock bolt?

And last but not least... whats the best size rod end shank to use? 3/8? 5/8?
And what kind of rod end would be best? the "clevis" style or the balljoint style?

Thanks,
Jonathan
