Did you ask him if he was one and the same Gordon Strachan? I bet he's been asked a thousand times, at least over the phone anyway!
Nice job persevering with this and finding an alternative to a 5 speed 'box!
Serious head on now! Did you use the backlash and depth of mesh settings recommended by NTG, or use the original English diff settings?
Did I read in your post somewhere that you deviated from the recommended settings?
The reason that I ask is that his first production run of 3.3 CWP's recommended 0.004" only whereas Ford specs are 0.005-0.007".
Also, are the depth of mesh settings (ie pinion shim adjustment) the same, or slightly offset against original Ford tooling?
Tighter backlash settings than factory spec bring the contact patch down towards the toe in a Ford diff (and should do in all hypoid gear sets). I wonder if this is how all his CWP's are, or whether the contact patch is still in the correct place with a tighter backlash?
