R33 Manual Conversion

[Sanj]

so i've converted my skyline from auto to a manual was quite easy to be honest everything works fine eg. reverse lights and such , but my speedo meter is not giving a proper reading i know i can replace my cluster to a manual 1 but i dont want to so that, was wondering if any 1 else had this same issue and has a solution

How far out is the reading error? Is it just because of the diff ratio difference?
