F150 TIMING CHAIN MARKS

2002 Ford F-150

Engine Mechanical problem
2002 Ford F150 V8 Two Wheel Drive Automatic 106000 miles

I can not find the copper link on my timing chain. Is there anything else I should be looking for. This is my first time trying to set my own timing. Didn't have a choice was layed off. I'm very worried that I'm not going to do this right.

please help

Installation
CAUTION:Timing chain procedures must be followed exactly or damage to valves and pistons will result.

Compress the tensioner plunger, using a vise.
Install a retaining clip on the tensioner to hold the plunger in during installation.

Remove the tensioner from the vise.
If the copper links are not visible, mark two links on one end and one link on the other end, and use as timing marks.

Install the timing chain guides.
CAUTION:Do not turn the engine over with the camshaft positioning tool or damage to the camshaft sprocket or the bolt can occur.

Install the Camshaft Positioning Tool.
NOTE:Slightly loosen the camshaft holding tools to allow slight camshaft movement.

Pre-position the camshafts.
Rotate the LH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 12 o'clock.
Rotate the RH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 11 o'clock.
Tighten the Camshaft Holding Tools to maintain camshaft pre-positioning.
CAUTION:Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur.

CAUTION:Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and valve damage can occur.

NOTE:The number one cylinder is at top dead center (TDC) when the stud on the engine block fits into the slot in the handle of the special tool.

Position the crankshaft so the number one cylinder is at TDC with the special tool.
Remove the Crankshaft Holding Tool.
Install the crankshaft sprocket, make sure the flange faces forward.

NOTE:Make sure the upper half of the timing chain is below the tensioner arm dowel.

NOTE:If necessary, use the Camshaft Positioning Tool to adjust the camshaft sprocket slightly to obtain timing mark alignment.

Position the timing chain on the camshaft sprocket with the camshaft sprocket timing mark positioned between the two copper (marked) chain links.
NOTE:The LH timing chain tensioner arm has a bump near the dowel hole, for identification.

Position the lower end of the RH (outer) timing chain on the crankshaft sprocket, aligning the timing mark on the sprocket with the single copper (marked) link on the timing chain.
NOTE:If necessary, use the Camshaft Positioning Tool to adjust the camshaft sprocket slightly to obtain timing mark alignment.

Position the RH timing chain on the camshaft sprocket. Make sure the camshaft sprocket timing mark is positioned between the two copper (marked) chain links.
Position the RH timing chain tensioner arm on the dowel pin and install the RH timing chain tensioner.
