Maybe a service tech can help with this?

The right rear speed sensor on my '95 Firebird Formula (LT1) with traction control cracked causing the TCS OFF and ABS INOP indicator lights to illuminate. I believe this is what is known as a 4 channel system. Unfortunately, the sensor is no longer available from GM and I haven’t found a replacement in the aftermarket. I believe this is because the car is OBD 1 using an OBD 2 port (applies to many 94 & 95 GM models), in other words an orphan.

I THINK the sensor part number (obsolete) is 10456264. I heard that the replacement is 10456535 which is the part number for a ‘98 and newer Formula, OBD 2 /LS1 car. I would like to avoid buying 10456535 only to find out it doesn’t work with my OBD 1 PCM.

Can anyone help? Much Obliged
