This is a copy of the 74 parts book with the pinion gears for the speedo. You might want to print it out. I have no idea which one you need.

 

[mopar-man 3000]

alright but as far as the tire size goes is it refereing to width and rim size

No..it's the actual rubber tire size stamped on the side.

They are refering to the thin strap that often gets buried in the crack of your butt. Rim size of course refers to the inner rim. With a proper rim measurement you may avoid surgery to remove that strip. Remember not to wear white pants, and always wear a belt with that speedo thong of yours.

The ones listed at Year One will not work in this truck. The pinion is all metal and has NO colored gear. The pinions at Year One fit into the tranny, on the 4x4 truck the pinion fits into the transfer case. The correct one looks just like the picture in the parts book I posted.

You cannot install one in your transmission. Follow your speedometer cable back to the transfer case, remove the cable and then remove the speedo gear. Count the teeth on it so you know what you have. Then use the above chart to convert the tire size(height) to something close to yours. I don't know if Mopar can still order these pinions. You might also consider going to an instrument/speedometer repair shop and ask them what they can do to calibrate your system.
This place has some good info on tire size,etc.

Chump on a side note do you have a parts diagram for a 1984 D60 lockout hub?
