What type/model diff do I have?

[Grass]

The M78's were what was in the old , XE's and the Late model camira VN, VP's, so I'd bet it the solid axle.

I could always ask next time I am having a beer with one of the Dana boys.

With the ratio's they could be right, as I think the XR's take the speedo reading from the anti-lock sensors on the wheel hubs, not from the gearbox.

VK to VS were 75 series Borg warner, as were to XF. IRS commodores to VT V6 were 76 series, VT V8 to current are 80 series. EA to AU are 78 series, as are BA I6 N/A. BA T and V8 are M86 Dana.

Turbo and V8 utes are also M86. 3.73 are available for both.

You wouldn't know how much for the 3.73 gears would you???

With the BA (this was sortof answered before) the only thing that changes speedo readouts is overall rolling diameter of the tyre.

I'm sure if you rang ford or their supplier you would be able to find out exactly how much and where from.

Yes Guys I appologize, both the M78 and M86 come in both Solid and IRS..

They are pretty much all Borg Warner / Dana (shame sh*te)...

M78 is a 7 and 3/4 inch ring gear, the M86 is a 8 and a bit inch ring gear...

M75 were a 7 and a half inch ring gear
