Tail light Lens Seal mod
this mod is also easy, it works on any
Series 3 XJ-6 and XJ-12 body style,
1980 to 1992, maybe on Series 1 and 2.
Go to a home improvement place like Lowes
or ACE and get a package of 1/4" thick
Window Screen Rubber Beading.
This beading is a perfect replacement for the
original foam lens seals.
