I have now found a source of an imperial size seal measuring 3/8 inch thick and which allows my boot lid to close properly, probably the same as originally fitted ex factory.

The company is Vintage Supplies, Happisburgh, Norfolk, NR12 0RX, (England) , Tel no 01692 650455, website www.vintagesupplies.com and the seal is reference SSSF (apparently a Bentley boot trim !! )"

Addendum May 10, 2005:
Also good dimensions on a boot seal from Macgregor British Car Parts in Ontario Canada
 
Addendum January 30, 2006:
Good dimensions reported on a boot seal from Bob West in the UK.
Also a good report on boot lid seal from Scaroborough Faire.

Addendum July 10, 2010:

Moss Motors solid rubber seal on left. MacGregor soft and hollow seal on right. See the science in the BIG DIFFERENCE in article BD-116A in the body section.

"Based on your comments Moss changed supplier and had new hollow type seal manufactured for this application. All supplies to both Moss US and Moss UK have been of this type since late 2010".

Addendum March 29, 2024:
There have been continued objections to the Moss hollow seal being too thick. Now it looks like Moss Motors changed suppliers and screwed up again. Picture at right shows the good MacGregor seal on left and the current supply Moss Motors USA seal on right. Not even close, and absolutely impossible to fit. Send it back.
