RPO Codes

Does anyone know of a good source for RPO codes for a 1985 Regal? I have figured out most of the codes, but there is a code FFL that has me stumped. My guess is that it has something to do with suspension (maybe soft ride).

"Option Codes" are just that, for items which could be ordered OTHER than factory standard equipment. In many cases, these will coincide with "Production Codes" or "RPO" codes, but many will not as standard equipment items also have production codes which will not appear in any option code listing.

Spring codes are one example . . . they might be tied to a particular suspension calibration, but they'll not be in any listing other than for replacement part numbers for springs (usually they were in a chart keyed to a "tag number" or the amount of weight they were designed to support, which many times had a three letter production code with the part number also on the tag).

Just some thoughts,
