G'day all, I have an '83 RN41 2wd Hilux into which I'm putting a 5 speed box out of an '87 Hilux. Not sure which box it is, some people tell me G52 some say W52. I'm also putting a KUN26 rear diff centre with 3.58:1 gearing. With the cable driven speedo what driven gears are available? How do I calculate which driven gear I need? I haven't chosen wheels and tires yet so that will give me some wiggle room. This is all part of a Commodore V6 conversion and I'd like to get the right driven gear in before I install the engine and box. I'm hoping to keep the original instrument cluster for that 'Retro' look. Thanks for reading, any info appreciated.
