Quick Question on Camburg Uniball UCA's

Just purchased a used set, gonna have to spend the $320 anyway from camburg to get the whole kit, uniballs, spacers, new bolts, new bushings etc. Now i contacted Camburg and they couldn't get me an answer on what center bolt I have on the old uniballs. The ones I have are black and use a large hex wrench to tighten down, unlike the ones on Camburgs website that are gold and use a hex socket to tighten. Anyone know what I have? Older style bolts maybe? Thanks

 

that looks like a grade 8 allen key bolt that was probably put on to replace a bad one at some time.

 

Were they replaced by Camburg or were they just store bought grade 8 bolts?

 

most likely store bought
