I'm pretty sure they do do don't buy them off eBay though because they charge you £200 postage, you will get the side window blinds for from o'leary's motorhomes, and the front window blind from Southdown motorhomes
I have the factory fitted side opening blinds. Could you please tell me if this product gives the driver more of the windscreen to look through. Like most, I find that the standard blind frame obscures from the top.
If you put the blind in the fully open position and the two pieces of cord which are either side of the blind there is a small steel clip on the top with the screw in it loosen the screw and move the steel clip down the cord slightly and then reattach the cord to the top of the frame and then try closing your blind to see if it's just picked up the slack it's a bit of trial and error but that should sort it out
