I know as well as being a buisness man, that you have to honor what you say. I build heads and intakes for guys all the time, and although I may be a couple days or so late, I call my customers every week or better and let the know whats going on, if I am ever late. The key is to keep people updated. Flanges are only a couple hundred dollars, but many of these people that ordered flanges, was done a year ago. I could not sleep with letting my customers wait a whole year after taking deposits or full payment. I am not trying to talk down justin by any means, just giving some advice. My suggestion is to not take any payment untill you have the parts in hand, on production runs, then no one has hard feelings. I guess I am just speaking from one vendor to another. I guess the key thing, is to make PERSONAL contact with your customers that have paid. PM's or email, or even a phone call. Rap some old cardboard, and a bunch of duct tape around the flanges, and send them off! They are durable, they wont break!
