To add to what GMsucks said:

Find some dry pavement.
Do a burnout.
Get out of the truck, count the number of stripes:
0 stripes = check truck for Ford emblem
1 stripe = open differential
2 stripes = anti-spin/limited slip/posi-traction
3 stripes = put down the beer, call a cab.

If you're buying from a dealer, they can run the VIN, show you a printout of exactly how the truck was ordered (options, etc.), and any dealer-supplied work that's been done.

MAKE SURE you buy a truck with anti-spin if that's important to you. I found out the hard way that just because it's a 4x4 doesn't mean it's installed. Cost me $875 to get it installed at the dealer ($435 for the differential, $50 for two bearings, the rest was labor and fluids).

 

Thanks everyone, I am now the proud owner of this lovely 03 model.

 

i got the same year color and every thing, its the best truck i have ever driven only thing i dont like is that licence plate in the front i had to take mine off i cant stand plates in the front

 

I hate it too, but it's the law here in Texas [sm=smiley21.gif]. But I have never actually heard of anyone getting a ticket for not having a front plate

 

man that sucks i was born in houston but dont remember that law guess i been away to long, i just had a chance to look under my truck and it says 'track lock' i pretty sure its positrack but what does it mean?
