Dan,

I had the same problem with my 1990 300 SL. I let the dealer do the job. The charge for the insulation was $81.90 ( I think Fastlane has it for $53.00). Two glue trim cements were $15.90 and one hour's labor was $69.50, bringing the total cost to $167.30. Your cost to do it yourself should be about half of this. Did you try the search feature? I think I remember seeing something on this before.

Bob
