Autometer speedo calibration to car

I have a set of Autometer gauges, the reverse wind 180mph speedometer and the right angled gearbox, I looked on the AM website and they had this information on the speedo:

The speedometer is calibrated for a 1:1 drive ratio (1,000 RPM at 60 MPH input at the speedometer head.) "this was not specific to the cobra gauges!

My question is I know my final drive ratio option , and have Transmission charts indicating what small nylon transmission gear to use with what tire size and final drive ratio.

How do I work out what parts or information I require? - not a biggy as I haven't ordered a trans yet still researching!
