Would like to pick your brains again ref sliding side window seals before ordering.
I'm looking to replace my window seals on my 1990 westy, the chrome trim type.
I've been looking at the bundle kits which supply front, rear, side middle and rear window seals, 6 in total. I called one supplier (JK) and asked if the middle seals are suitable for the sliding windows (See pic) and was told they are not.

Does anyone know where I can get these seals from or have any other info regarding these seals. The usual searches haven't come up with anything...
Thanks again in advance...
Chris
