Where to find rubber bay-door seals?

[Geom]

I've got the occasional leak in one of my bays when it rains. It's not all of the time, but depends on the intensity and direction of the rain. The seals on my bay doors are all old, dry, deformed, and some painted over. I think I just want to replace them all, but can't seem to find anywhere to get them.
The 4107 parts book doesn't even seem to list the seals on there 

Anyone know where I can get replacements? I'm looking primarily for the ones along the sides, but would also consider replacing the tops if they're not a complete PITA (they're not nearly as bad off).
My attempts "jury rig" an equivalent off-the-shelf solution were a colossal failure

Luke can fix you up: 1-888-262-2434.

You do have his number programmed into your phone, don't you?

If not, you should!
