Thanks, Ron. By the way, that's a nice Vicky in your avatar. tdlmomowers, 4-speeds were available, but not many were built. I used to know how many, but don't any more. The gauge cluster is out because the wiring harness caught fire right behind it. That was a little scary. I think the ignition switch fell apart and grounded out, starting the fire. If anyone out there has a wiring harness, I could really use it. I have 2 from '65-'66 Galaxies, but they dont have all the gauges like Mercurys do. The '65 Galaxie donated a clutch pedal and complete linkage too, so I may go the 4-speed route. Comparing the S55 to it's 7 Litre Galaxie cousin, two things stood out right away. All of the 7 Litre cars came with front disc brakes, and an open element air cleaner. The S55 came standard with drums, and a single snorkel air cleaner. That little snorkel is just barely 2 inches across, and has no provision for warm air. Also, for anyone looking for 31 spline rear ends, all the ones I have seen for 1966 Full-Size cars have the left axle flange painted red, and the right one is painted green.
