STEP ONE: Determine proper running board length
1) Measure from the rear of the front wheel well, to the front of the rear wheel well. This should be your overall running board length.
2) Measure from end tip to end tip of the running board to determine how much needs to be cut down. (if any)
3) Step two minus step one is how much needs to be cut off the board.

STEP TWO: Cut running boards to proper length
1) Remove the 4 nuts holding the removable end cap in place.
2) With the end cap removed, measure and mark a straight line to cut off the proper amount of the board. (determined in step 1.3)
*NOTE- At this time there should be no light wires under the board.
3) Using a table saw or hacksaw cut along the marked line thru the plastic
and aluminum.
4) Replace the end cap and tighten it with the four bolts and nuts making
sure it is square with the rest of the board. The end cap should slide
back over the board about ¾" - 1".

STEP THREE: Determine proper bracket placement
Fig A
1) Equally space brackets so they can support the weight.
2) Mark and drill holes into the pinchweld.

STEP FOUR: Loosely bolt brackets to vehicles
Fig B
1) Bolt the brackets on by hand tightening the bolt thru the
pinchweld and into the lower hole in the bracket.
2) Place the running board on the brackets with the support
Bolts falling thru the slots in the foot of the bracket
3) Hand tighten the board to the brackets using 5/16" lock nuts
4) Slide board in or out to desired location
5) Tighten down lock nuts under running board

STEP FIVE: Tighten brackets
1) Push board tight against vehicle and tighten bolts Fig C
2) Drive self-tapping screw thru top of bracket and into sidewall of truck to keep bracket in place.
3) Check that all brackets are tight before stepping on boards.
