Joćo,
I measured up the channel in my truck, and while it is approx. 1/2" high, the width less than an inch (approx. 7/8"), rather than the 1-7/64" (or 1.11") as per the picture in the catalog.
Now, the channel in my cab window is too narrow as the steel sliding plates can only be moved with much force (can't say they are "sliding", really).
But I do not know if the width of the SPAENAUR twin channel will fit the frame.
Who has tackled this job before and can help?!?
Hanno
