Just take a 12mm wrench and a 14mm wrench to your studs
See which one fits
Sure, there are probably numbers you can research, but time is money
Good luck
The 12mm has a 3/4 socket that fits
The 14mm needs a 21mm socket

Thanks, mine needed a 21mm socket so I will need to use 150 ft lbs of torque.

I think that they changed to 14 mm in 2000.

Yep, 150 ft-lbs. That's a lot. Scary.

I bought a 1/2" breaker bar and socket from Harbor Freight to keep in the back of the truck for that reason.

Make sure you have spare tyre release crank rod too under the hood! Mine was MIA when I purchased this truck I am always perplexed when those vanish along with all floor mats

True, it did that me some time to figure out how to remove the old spare tire.

Thanks, maybe you should try to see if you can do it without a extension pipe, I could barely remove my 100 lugs on my car, it only had 100 ft.
