Hard to tell from the photo, but you may be seeing the remains of an old shok-buff (Shok Buff). Wilson and others make them, they aren't always blue as the one in the link, and they are life limited. You can replace them inexpensively, and they offer some protection against frame battering, or you can leave them out, as some folks think they add an unnecessary point of failure.
You could get a replacement guide rod of standard length from Brownells, Midway, or a bunch of other suppliers. The full length rods can be a pain in the neck, but you do see them on high-end guns like your Wilson because they slightly improve accuracy and reliability. They're also cheap, and are a drop-in replacement. You could pick one up and see if you can tell the difference.
I have inherited a Wilson colt 1911 mk iv series 80 recently and after I had taken apart the pistol to clean I have noticed there were pieces of plastic that was broken off I believe where it used to sits behind the spring of the guide rod. After I had finished cleaning the pistol I am currently stuck at getting the bushing/guide rod down the barrel because the bushing is hollowed out which I have no problem pushing down with a flat tip screw driver but the guide rod would not go down enough for me to swing the piece to lock it in place. I was wondering if anyone could tell me if I need to replace the plastic piece that was broken off and also if someone could point me the right direction as to maybe replacing the full size guide rod to a shorter version? of guide rod (and where I could possibly order one?) maybe that will solve my problem. TIA

I concur with @JohnnyB . This is a total non-issue as you're maintaining both as residences. Buy 5 more and you'll get the same answer Both residences are where you'll be residing, so BOTH are EXEMPT LOCATIONS.
@lhrocker So now we "pull teeth" to get the full story:
Are both houses in the same town being used as YOUR residence OR is your intention to rent the old house to someone and transfer all your worldly possessions, including your firearms, to the "new house"? If you're moving out of the old house, and changing your driver's license, you'll need to get a new Yellow Card.
Even if you rent it out, it's still property YOU OWN, so you're allowed to patrol it armed. Hair-splitting is a specialty of mine, so...
You can own many houses (or vacant lots) in NJ's 21 counties, and carry or store firearms at any of them, provided they are secured and away from prying hands...OR transport any number of firearms TO them at any time day or night. I've written about this several times in the past.
