                neat-o. Probably nothing I would change.... when the inspection is up this year on my 1990, I think I am going to retire it from daily driver service and garage it to work on and restore (body work, build engine, et al).

                I can get a 5 year old CVPI at auction for $1k and will probably get one to use as a DD - I'm trying to find out as much dirt on them as I can.

                      If you can get a pic of the sticker on the drivers side door, that would help immensely!
                      GMN member Good Samaritan has the a list of all the axle codes in his signature.
                      Even better, a pic of the axle tag. It's on the differential cover. If it has a "L", than it's locking.
                      I found a 3 55 L in the junkyard. That's 3.55 gears and trac-loc. I took that trac-loc!!
                      Ask Pantera77. her was there during that escapade in the junkyard in the middle of January.
                      K. hope this helps....

                        Who got 3.85's?

                        That seems high for a factory 80's ratio, anyone know of any cars that had it?

                            If it's a trac-loc, it will look like 3L27 or 3L55 as opposed to 3 27 or 3 55

                              My 93 interceptor had 3.27s open rear. I think police departments order them open so the officers are less likely to get sideways and crash
