My right turn signal/braking light keeps goin out. Every time i pull it out and fiddle with the bulb it ends up working but only for short while. The plastic 3 wire housing/socket the bulb is screwed into is all nasty lookin and im convinced this is the weak link as the wires have continuity and the bulbs are good. The one i am looking at is the middle of the 3 bulbs/sockets in the tailight housing.

I order alot from Rockauto.com and they have these on there but there are bunch of different part #'s and the pics are all the general type pics that dont necessarily show the exact part. Here is a link to one of the listings there...http://www.rockauto.com/catalog/moreinfo.php?pk=943059

Now, this looks exactly like the part needed but if u look at the other choices there are like 3-4 others with the same looking part but numerous other alternate/OEM part numbers. Anyone know exactly what part number i am looking for or will any of these work?
