production date

[LeBronCo]

I'd like to put new shocks on my 1989 Bronco II. But it seems there was a change in the lower bolt size some time during the '89 production year. 10mm lower bolt thru 01/89 and a 12mm lower bolt from 02/89-09/89. How do I determine what month my Bronco was born from the Vin? Thanks for the help.

There should be a tag on your driver's side door jamb with that info. If you need help identifying it:
