Gray Ports
Keith, I just put a full set of new Gray ports in my 79 H33. The handscrews on the new ports are all plastic, without the insert of the originals. I think that this is an advantage, since they are not prone to freeze as as happened to you. Also, it may serve to emphasize that a lot of torque is not necessary to seal these ports. Best way to prevent them breaking is to just torque them down just snug and no more---and prevent hand handed visitors from torqing them down. There are also a couple of other improvements on the replacement ports. The drains are now molded integrally into the ports rather than having a separate clear plastic drain, a definite advantage eliminating the possibility of leakage into the core of the trunk cross section, though it does require a new cutout to match them. Also, there is a third hinge in the 7 x 14 ports in the middle, reducing flexing there and the possibility of the lens cracking. I took a lot of photos replacing mine and will post when I work out the technique of the photo forum.
