Can anyone recommend a supplier for the 2 small metal pipes connecting the solenoid assembly mounted on the right front of the intake manifold to the distributor vacuum advance and the rear of the carburetor? One of mine (lower) is okay, but the upper is bent beyond the point of using it and being able to contain it in the clip. These would go on a late July, 1970 with LS5 (AIM page K349, parts 9 & 10). So far, all I can find from the usual vendors have been discontinued.
