Nice!
PO did you one hell of a favor, as V12s weren't sold in the states with manuals after 1981 and instead got a GM 4 speed auto. Three pedals is the way for all the things, really. A slushbox Tom Walkinshaw tribute would be daft.
The biggest favor he did you was the wiring harness replacement. Lucas used incredibly thin wires for tasks that needed thicker wires, so the if the things worked, they would get hot and melt insulation, then cause shorts or worse. There are a series of jokes about the fellow and his company. "Why do the british drink warm beer? because lucas made their refrigerators."
I bet it sounds amazing. Does it have the sidepipes, or at least a set of cutouts?
Because rust is a thing, I drove my 240D a bit with no muffler. It sounded like a World War I fighter plane. It was absurd that something so slow could be so fantastically loud.
