On my 69 RR, my one park lamp (bumper mounted) has a rusted out bulb socket. The housing is fine, I am looking to change out the socket-pigtail. I bought another housing/pigtail from an a body and want to swap the good one into mine. Has anyone tried this and know the proper way without messing up either the housing or the pigtail/socket? It appears to be crimped in on the inside of the housing; where the bulb goes.

Just trying to get some good advice from someone who has done this before I attempt it. The B body housings are not reproduced and are hard to find, so I am trying this way first. Pics of what I got and then the new one that is on the way:

Thanks,
Mark
