How to tell if I have 4.10's?
When I bought the car the guy SAID he and a buddy had 4:10's put in at some point when he owned it at a shop. Shop had no record of his name in the system, but that's not to say it wasn't done under another name (like his dad's).
Any simple way to tell if that's what's really in it?
Thanks in advance fellas!

Dont pop the cover on anything. Get a GPS and check your speed against your RPMs. Stock gears are like 2K @80MPH the 4.10s will be much higher.
*I say GPS because it eliminates the possibility they were installed and never had the speedo corrected.

Fill out the info on the left and it will tell you what your speed should be based off RPM and what gear you are in.

68-70mph in 6th gear would be 1800-1900 rpms if it were 4.10s in the rear. 2000 rpms in 6th gear at 68-70mph, would be closer to 4.56s same thing with what you originally said about 1800-2000 at like 60-65 mph, that is just about right for 4.56s.
