99 Ranger XLT production month

[dazzy]

Changing head gaskets and the local parts store has to order the set in, they need to know what month (before or after May 27th I believe) it was made in, the sticker has been missing from the inside of the door for years, is there any other way to tell what month it was made in?

I've tried using the vin number it just shows the year.
It is flex fuel if that matters, 3.0L v6

Have you tried the VIN decoder at compnine.com?
