Re: transmission
Best way I've found is road test Billy. Not much help if you don't have a gear to start with. They usually have around 20 teeth. Each tooth you add slows the Speedo by around 5%.

Re: transmission
You'll need to know what colour drive gear is already inside the box. You can then pick a driven gear to suit (can change both if needs be).

Re: transmission
Billy , TCI transmissions website has a real good calculator, also tells you what colour the gears are so you can see the colour of your drive gear inside the box and try and match a driven gear to it - all you need to know is your diff gear ratio and rear tyre size , if you don’t know tyre height there is a calculator to work that out online too just Google tyre size calculator and put your size in and it will give you the height
When you're faced with an unpleasant task that you really don't want to do, sometimes you just have to dig deep down inside and somehow find the patience to wait for someone else to do it for you.
