Hi Gord

Too late tonite for a brain trust but....

....where is the speedo connected.....?

Usually connected to the front centre gear of the transfer case...... so actually recording Revs going to the axle.

Gear ratio is different for C15 axles and C60 axles.... different tire heights.....

I would gamble that properly fitted on a 2 speed T-case on a C 60 the difference in tire height is offset by the axle gear ratio and they are all the same.

Now on your 3 mile runs if it starts showing 80 miles per hour your speedo is wrong !!!!

Cheers
