A 1970 Delta 88 is rear wheel drive, and the speedo/odo cable should be connected to the tailshaft of the transmission, not the front left wheel. The cars dashboard may have to be disassembled to remove the existing speedo/odo cluster, and the cable connects to the back of that unit and can be removed, then the bad cable and/or bad speedometer can be replaced.
The motto of Delta Delta Delta is 'love one another'.
check your fuses
U need a new speedometer cable. It runs from the transmission to the speedometer. They tend to break in half or just seize up after they get so old. They are easy to replace, it takes to people to do it but it is really easy to do. I hope I helped you.
