Charles, I had a window leak last nite, so today I was out there with my chunk of weedwhacker mono but it just wouldn't feed in. Whilst messing about with it, I discovered the little plastic hood on the frame can be removed and replaced (it can also be lost if you drop it in the wrong place, but that's another story), it has a bending clip on each side.
With the hoods removed, I was able to put a thin metal rod (small bronze braising rod) all the way across, from one opening to the other, without bending it. In the process, I removed a plug of mud and calcium chloride (courtesy of Canadian roads,esp Yukon Terr) about 3/4 long that wouldn't budge for the mono.
Sure wish I had the crankout
windows on the rear; I have had zero problems with the ones on the side and they give more ventilation and protection from rain.
Pete, wondering where to get another of those little hoods, and Rats
