Rocker arm

1999 F250 Superduty Triton V10

I have a miss on #5 so I changed all the plugs & #5 coil. I then got a miss on #5 and random multiple misses.
Next step was to do a compression test on a few cylinders, which was fine, didn't write them down. But #5 compression was "0". I then pulled the RH valve cover off and found what I expected, the second to the last, intake(?), rocker arm laying in the head.
I ordered a new rocker arm and lifter & gasket. How do I get it back together?? I read about a special valve spring compressor for this engine series but it is #5!! Right next to the evaporator box.
Any suggestions would help big time.

might can rent a tool from local parts stores. The Ford tool in the photo uses a ratchet to actuate the valve spring compressor.

I'm a little confused. is the spacer (303-382) a guide, of sorts, or are you pushing on the spacer? I would think you would need to push on the valve spring retainer, on top.

OK I see. Spacer limits travel and push on valve spring retainer.

prevents you from compressing spring too far and the valve keepers come off dropping valve into cylinder.
