The threaded bolt on the upper RH side was used in place of the stock bolt that came from GM. The '94 Astro piston assy is no longer available from GM, this forced me to use one from a '00 GMC HD truck. Problem is, there is some difference in design apparently, the piston is a little shorter than I needed, hence the replacement bolt.
