Identify Eyebolt Locations
Refer to Figure 4 (showing both suitable eyebolt locations on
one side of a baffle - only one eyebolt per side is installed)
9. Select one (1) new:
15
804-007C WASHER FLAT 1/4 SAE PLT
This is used as a template for marking holes.
For use, prepared baffles ( , ) are held in place by
straps which take a diagonal path across the top of the
baffle (the dotted double-arrow line in the Figure). They
attach to eyebolts supplied in this kit, which are installed
in the nearest corners ( , ) of the adjacent seed box
wells.
Depending on vintage, your drill may or may not have
1
bolts in suitable locations. If it does, these bolts may
be replaced with the eyebolts in this kit (holes are drilled
otherwise).
10. Check the seed tube wells immediately adjacent to
the baffles. Suitable hole locations are in the cor-
ners closest ( , ) to the baffle. Do not use the
outside corners (this can cause the strap to inter-
fere with the sliding seed tube, as well as obstruct
seed flow).

Mark any bolt heads at suitable locations. At the
diagonally opposite location, mark any bolt head
there, or use the washer to mark a hole location.
