I lost both my front lens on my 378TS while driving the highways. I couldn't find any online, so I just went to O'Reilly's and got two whole lamp replacements for about $8.00, if I remember correctly. Took me about 30 mintues to remove the old lamp and replace them with new fixtures. I figured that it would cost about the same if I could have found the lens online and then paid shipping.
By the way, sorry for your sagging headliners. I had my dealer replace mine twice, and now they are sagging again. I would recommend that you get someting from your dealer and FR to warranty their work for several years out. I didn't, but wish I had.
