Just an FYI, the above listed tail seals may be too big. Not sure, but maybe. Tail lamp sockets still used the 1156/7 style of sockets, but not sure if they changed the size depending on front or rear socket thickness. Probably worth the price to see if they do what you want them to do.
If you can't find suitable gaskets, the socket comes with them preinstalled.
I had GM part numbers for the sockets somewhere. Just got to find them.
Aha! Found the mofos. For Monte and Monte SS, Socket- GM p/n 12013813 for the front parking light/turn signal. 2 per car. ACDelco p/n LS8. Gasket is included. Most G-bodies used this socket assembly. Can also be used for some tail lights, but not for your Monte SS. It uses 12003757 sockets for those, ACDelco p/n LS6. They kinda go sideways and lock in with a push in tab.
