He mean’s the tail light gasket’s.
And it is recommended if you remove the tail light’s.
Because after 14-17year’s without removeing the tail light’s, The gasket’s tend to dry up and come off in pieces.
Which cause tail light and trunk leak’s. I have the tail light leak in extreme wet condition’s. 
Oh, right, yeah that’s a good idea. Both of my DAs had leaky trunks!
Are 2 door and 4 door tails the same size… reason why I asked cuase my DB drivers side is cracked and i found a good deal on OEM ones… thanks
no, very different.
2 door tails are 1 size that isnt the same as the 4 door tail size.
If i’m not mistaken 90-91 4 doors and 92-93 4 door tails are not the same size either but you can put 90-91 tails on a 92-93 or 92-93 Tails on 90-91 if you change the trunk lids to match the year of the tail light.
Thanks for the info guys… well im waitin to hear from the seller…he didn’t specify on the add if they were for a 2 or 4 door…
