Question:
I had an Invisibrake system installed on my 2014 Fiat 500c a while back and one of the 2 screws holding the front plug-in assembly is missing. I think my installer may have forgotten to put in second screw. Ive been using it with only one, but it moves around when I try to plug in the cable and Im afraid that that screw flange will weaken over time and break. I havent been able to match the hex-head screw so far. Can I purchase one from you, or could you tell me what to look for and where. Thank you for your help.

Hello Mike,
I see that you’ve already ordered the screw that will work for the front plug on your 2014 Fiat 500c. The Hex Screw - Self Drilling Unslotted Washer Head # 101131802 (#8 x 1/2") will be a great fit for securing the RoadMaster 6-Wire Trailer Connector - Vehicle End # RM-910030-7 nice and snug.
