Hi
Sorry I missed your post there after you installed the reg! Sounds like you had multiple problems... The rotten rubber could easily have been from the fuel ....we've had ethanol in the fuel for a considerable time and I've talked to some guys that say they have had one heck of a time with deteriorating components. The only thing I've found is that some rubber accelerator pump plungers that come in carb kits (blue in colour) for Holleys turn into a spongy blob, yet the orange silicone ones last. Either way Looks like you're on your way to enjoying your LeBaron!!
