55.2-59 58-59 Fleetside Tail Lamp Question

[QBRacing]

Hi all...

Just doing some wiring and I have a question regarding the tail lamps.

1) Do they have a gasket at all between the lens and the housing.
2) If not does that same face then meet the whole way around the housing/lens as mine only seems to fit 70% of the circumference.
3) does anyone sell repop tail lamp housings (i can only find lens's)
4) does anyone sell a screw set as my truck came torn apart and I dont know what they look like (read cant find in the misc screws box i was supplied).

Regards
