[Chrysler300] 1963-1964 300J-K

Historical/technical questions for the J-K crowd:

Did all 300-J’s have the 150 mph speedometers and tachometers?
Were the 150 mph speedometers and/or the tachometers an option on any other 1963 Chryslers? Maybe special order?
Did any of the 300-K’s or any other 1964 Chrysler (including police cars) have standard or optional 150-mph speedometers and/or tachometers? Seems I had heard or read that all 30-K’s with four-speeds had tach’s instead of vacuum/performance gauges.
Did any 1963 or 1964 Chrysler with a 150-mph speedometer have a different speedometer pinion gear—or were all calibrated to the standard 1,000 RPM @ 60 mph?
I do recall that the 1963 300 Sport Pace Cars had compasses mounted in the consoles. Was that option offered on any other ’63 or ’64 and did those work OK?

FUN-WITH-NUMBERS

I just ran some calc’s for 8.50 x 14 tires (28.10” OD); no tire-to-road slippage or wiggle-woggle, 3.23 differential ratio; 150 MPH requires 5,797 RPM at the tail shaft. 140 MPH= 5,411 RPM. Possible for a J or K?

C300K’ly,
