If you have trouble getting the old striker off, I tried a star point bit, it just striped out the striker. I tried a pair of Vice grips, a large pair of channel lock pliers, Use a small pipe wrench, it works like a charm.

Just wanted to add, that I did this fix as well, and it worked perfectly. I didn't know my doors could be so sturdy! One thing to remember, it takes a little extra effort to open/close the doors. Make sure your door is fully closed when you go driving.
This helped my driver's door somewhat, but didn't get rid of the rattle completely. However, wrapping some electrical tape several times around the striker for some extra cushioning silenced it the rest of the way. It really needs that cushioning, when you shut the door it now feels firm, secure and quiet. I assume that the layer of rubber in the door latch originally has worn through and is mostly metal-on-metal now.

The Ford striker bolts completely rid my 88 of the rattle, you could actually push pull the drivers door 1/2" with the window down and here it bounce over bumps. Passenger side is never used and it was fine but replaced it and it also shuts firmer.
It does have 100k on it, but I would suggest anyone that does or even doesn't currently have an issue to replace them. Seems the stock may be a tad too loose.
