Could be any of several. Check the little metal tag bolted to the diff. That truck also likely has a 8.8 rear, not a 9 inch. If the tag says "88" it's an 8.8. The gear ratio will be stamped with no punctuation, i.e. "327" would be a 3.27 gear.
8.8

No, the bolt 219 W is not the correct size bolt for the 1989 Ford F150. The bolt pattern for that make/model of vehicle is 5.5 x 5 lug. The F150 is one of the larger trucks that Ford manufactures.
