You are good to go. You are right that a 1/16" isn't going to matter either way on the length of the axle.
Brian no need, those are the measurements after I cut the six foot rod. I was close to dead on 22 inches, off by a sixteenth in each direction on two and dead on on one.
Thanks!

No Tim what I meant is trying to find out if my local Grainger has those in stock avoid the shipping charge. I work for a big blue company so actually since we have a relationship with them see if the local rep might comp me one and deliver it to my office. Free would be good.
