    I love the marquis speedos. I forget what 140 I have in mine. The digi dash in my town car read up to 120 after the chip got rid of the limit of 107. It still pulled past 120 but didn't register iirc.

        The 135. It has a 140 mark. Caught it on a Facebook video.

          Oh that’s weird looking. Looks like an ‘88-‘89 dash, so I wonder what the reasoning for doing that was even though 140 variants exist in that style too.

            I second that looking odd and different. Cant say Ive seen that before. Almost like an overlay. The surface looks so flat.

              Hate to revive an old thread, but is there any 140 cluster that will swap into a 91 Grand Marquis?

                yes, but only 90/91 years IIRC.

                  I take it the sweeping style clusters out of a Vic are different than the 90-91 sweeping style Mercury clusters?

                    90-91 Ford and Mercury clusters are styled differently but are functionally identical and plug-in compatible with each other.
                    Analog Lincoln clusters are also the same plastic housing but I'm not sure they plug in without problems due to Lincolns having additional warning lights.
                    Starting for model year 90, the speedometer is electronic, taking its input from the VSS (where on 89 and prior, there is a mechanical speedometer cable).
                    You cannot interchange pre-90 with a 90/91 without an absolutely massive investment of effort.

                    The 90-91 firewall, dashboard, cluster and all associated technology elements is far more similar to the aeros than to the boxes.

                    This is a Canadian police speedometer from a 90 P72 cop car in my 91 Mercury:

                      Are there by chance any of the 90-91 clusters that have a 100,000 mile odometer?

                        Canadian clusters are 6 digit starting in 84 - but I'm pretty sure American clusters don't get the extra digit until 95 (or maybe even a later year, but in the 95+ style cluster at least).

                        Whether you could use the Canadian odometer in the American cluster, I don't know. I bet you could, but I bet the odometer will count in km because of the electric motor speed and gear tooth ratios being set for km. Edit: the gears are the same in the US/CA clusters, so maybe you just take the motor out of the American odometer and attach it to the Canadian odometer assembly and it works. Maybe.

                          92+ have 6 digit odometers in the US. At least 93+ since my 93 had a 6 digit odometer. HAD because the internals of the speedometer (gears and some of the casing) started cracking and breaking so I have a digital Autometer speedometer with odometer hacked into my dash.

                            Oh, right, I kinda forgot that the new cluster was actually in 92, but only for Ford.

                            I know for sure an American 92 Town Car analog cluster (which is essentially the same thing as the Mercury cluster, and the Ford cluster that existed in 90-91) is still 5 digit, but the internet makes it look like 93-94 get "approximately the same cluster" with a 6 digit odometer.

                            So you could probably investigate hacking this together using a 90-91 140MPH speedometer and the odometer assembly out of a 93-94 Grand Marquis or Town Car (analog only).

                              I'm not certain about '92, I thought the 6 digit odo that I bought from someone one here (mcninetyone) had a '93 (F3) part number, but I might be imagining that. That 6 digit odo was installed in my stock cluster in The Ice Car then swapped into the '90-'91 police cluster. The police cluster was later swapped for a '98-'02 P71 cluster (nowhere near a direct swap), and the '90-'91 police cluster is in The Scab still today (since I haven't swapped to '98-'02).

                                I have a 180kph (100mph) speedo out of a 1989 crown vic that is also white letters/orange needle as the installed one above (but no square at 55mph on the Canuck speedos). I pulled that years ago from an 89 cv. Just something else to throw into the mix. I'll add a photo later, battery is dead in the camera.
