Drill Holes for the Passenger End Link
The driver side frame rail has an existing hole for it’s end link, but you’ll need to drill a hole for
the passenger side. But first we need to measure the driver side hole location. A good
reference point for the hole is the bigger hole near the edge shown in the picture below.
Measure the distance forward from the big hole to the little hole. It should be around 1.5”.
Go to the passenger side frame rail and measure the same dimension and mark the frame
with a paint pen. Drill out the hole using a 7/16” drill bit.
