trunk seals for 87 4kq

[lrickert at covad.net]

are trunk seals no longer available? Is they any other option such as a generic 
seal that works to prevent a soggy trunk? over the years I have resealed all the 
rear lights and checked all the other options I can think of but still end up 
with gallons of water on either side of my trunk when it rains.  The old seal 
doesn't fit tight and looks like the last posible option.  

thanks
