I am sure the small link, at A, is designed to allow fitment to the variations in seat dimensions. Altho pretty close, the seats we fit have all got to be a little different.
Along that same line of question or fact finding - The bolted joints at "A" are snugged down tight for no rotation or flexing. Yes or No???
Altering the "A" link length would vary the installed height of, what I call, the "V" rack.
These "A" links are installed to the outside of the seat, altho I have seen them routed to the seat inside.
This drawing shows the mounting at "E" points on the rack to be to the inside of the rack, but my rack & arms do not seem to allow this .....so my arms are outside.
The drawing also shows the rear arm with bend to rear, short section up........but if you flip the rear arm, on mine, it clears fender T nut.
Where are the Craven instructions for these racks?
