How do I find out if a truck I'm looking to buy has limited slip or not??

It's a 1976 F350 Trailer Special Supercab with a 460/C6.

Thanks!

 

On the axle tag it will have the gear ratio with a L in place of the decimal like this 3L73 or check the truck data plate on the door. This link from mil1ion will explain what the codes mean.

Oh, thanks! This link is for 1977-1979... will it work for a 1976, too??

 

I found out the VIN tag info... don't know if it's all here or not. I need help decoding this VIN tag on a 1976 F250 Trailer Special I'm looking to buy...

F2544CO4875 TRUCK F011-R432

GAWR Front 3850
GAWR Rear 4480

Does it have limited slip or not?

THANKS!!
