Help identifying rear-end ratio
I know that I should look at the tag on the door but, the truck has a replacement door and new paint, and no tags or stickers anywhere on the door or jam. I am hoping that based on the info I provide, someone can make a fairly certain guess at the rear-end ratio. I'm assuming there are only a few that it could be stock. The truck is 1994 F-150, reg cab, 300 I6, M5OD. It redlines in overdrive at about 92 mph. any guesses?

Help identifying rear-end ratio
I took the liberty of calculating the ratio with a 31" tall tire size and it gave me 3.55's at about 3000rpm... now if you calculate in wind resistance and other friction that should be pretty close to 4000+rpm. Otherwise you've got some serious gearing (and I don't think they came stock like this) and it's over a 4.10... or a big time drag in the trucks mechanicals.
