Speedo will work. Aftermarket ring gears are always narrow like that one on the right. Its the gear pitch (angle) that matters, not the width of the gear.
Ok just thought I'd ask cause I had the speedo head tested and that works got a speedo gear off dstocks and still no change just though that might be a reason cheers
The one on the left looks like it has a bigger bearing than the one on the right?
Hard to tell from the picture but it doesn't look like they have the same dimensions?
Ok this is the story the one on the right is the original 25 spline LSD diff out of my Fto and one day it completely sheered off the bearing the one at the top of the photo and the one on the left is a standard diff off bennoz and it's a 27 spline and I have a 27 spline LSD diff but bennoz thinks its a cusco and I hate the clunking now hahaha this one was front my wreaking Fto hope u can understand that little complicated
Cheers
Well the two FTO's I have are both 95 white gpx's and one had the small diff(mine) and the other had the larger one so no Idea how they worked that out
