Something has me a little puzzled.
A few threads back David you mentioned it was a “single shifter Dana 18 transfer case”
“Doctor Dana” would be able to answer this, what year did they switch from a double lever to a single lever Dana 18 TC?
This makes me wonder if it has in fact a T90 tranny bolted to a Dana 18 TC and if that is the mystery with the speedo and the ebrake?
