The ignition switch cover uses a rubber seal to help prevent water inside the ignition switch mechanism. Most of the covers I've seen have badly deteriorated rubber seals. Here are several suggestions on what to use for a replacement rubber seal.

We used Ford brake kit rubbers and believe they were from the 1980's.

These look more like it: O'Reilly Auto Parts part number 16000.

I'm sure the parts counter guy/gal or Ford garage could confirm.

Just take the old ignition switch so they can see what is needed.

Boot ID is 716 inch and 58 inch.

Worse thing is getting the backing plate off the old key cover. Use patience and carefully turn and pry the sheet metal disc from the white metal cover.

You get more than one useable boot out of each rubber. Rubber brake seal also works well as a cover for the police style clutch adjuster....

Toyotas use rubber sparkplug seals that are very similar...

I found them on Google as Celica, but another search indicated several models...my Ambo is in SoCal getting refreshed so I can't do a direct comparison.
