Hmm. You should not need the HD tie rods to work with our uprights. The gen1 version required it but the gen3's which you would have received should only require a spacer to set the gap and you should be good to go.
I also got your email which I would have preferred a chance to address first but I do understand your frustration. I will follow up with you tomorrow. I just need to verify who told you this and why. As long as I'm not mistaken we should have sent you the spacers with the kit and you should be all set. If we didn't send them we will next day some to you. If I'm wrong about all this then the website absolutely needs to be changed to note this and I'll get right on that as well.
