====== Land Rover Speedo Gears ======

^ Teeth ^ Colour ^ Part# ^ Comments ^
| 20 | Blue | FRC3310 | 7.50/16 or 235/85/16 tyres (or similar) |
| 21 | Green | FRC3311 | 90 except 50LE (whatever that is) |
| 22 | Yellow | FRC3312 | 90 on 205R16 tyres |
| 23 | Not listed | FRC9339 | Discovery 1 V8 Carbed |
| 24 | Red | FRC3313 | Defender V8, Disco 1 V8 EFI because red ones go faster ;) |

LT230 speedo drive ratio appears to be TEETH/10:1, so 20 tooth gives 2.0:1, 22 teeth gives 2.2:1, etc.

Although [[https://forums.lr4x4.com/topic/13529-speedo-cable-lt230-to-series-3-speedo/?tab=comments#comment-142082|this thread]] suggests the LT230 WORM (FRC3162) is common to all, but it's 9 teeth NOT 20 as suggested.
