15mm Rod Spacing?

[RileyRobertson]

I've seen on here before someone posted the standard spacing between the 15mm and 19mm rods, but can't seem to find that thread after looking for a few hours. It was all drawn up with measurments and everything.

Can anybody help me out? Thanks


Wow I started to look threw it again and found it....
