No - but I would have thought the progression might have shown you that BUT the BPPA is the most current. I actually do have a NOS of that PROM and I've posted them for sale before. You should be able to find the "for sale" if you looked. Parts cataloging confirms the part # and I don't have a '92 VIN to see your results but I would have thought it would have confirmed that.
