How do you replace the odometer in a 1970 delta 88. I know it is hooked up to the left front wheel but can find no way to hook another one in?

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.
