Re: Spid breakdown needed

I see this SPID already has the dummy character "1" filling in front of the RPO code, but still has some additional function name info following the code.

Tim - was the RPO code always associated with 5 tires?

During the squarebody era the codes were separated for front/rear/spare to allow for different tires front and rear.

XFL - Front
YFL - Rear
ZFL- Spare (or no spare)

Did '67-'72 ever have anything like that?
