No, I do not take payment until the product is ready to ship. The first 2 sets were ready/paid/shipped. The other 6 sets is a reserve list for the one that are in production now. Once those are ready (~2 weeks) I will notify them directly via PM.
There seems to be a larger need for these and the Compliance Clamps than what was expected. We have both slatted to go into production in September. I have quite a few other projects in the works also. I will try to get these Tie Rods and Compliance Clamps done asap.
