i think you mean 26 spline and 28 spline. and thats what i though also

IRS was also 28 spline. We have Borg Warner M78 diffs... 78 is short for the size of the crown wheel.. 7.8 inches

The Borg Warner M76 (7.6 inches) isnt used til the VT stock Ecotec.

And I just checked, and YES the IRS LSD centre WILL fit your live axle diff housing. So you can use the LSD centre.

I think the VP(V6/8)-VZ?E(V6) IRS centre is a 7.6 inch and the live axel is 7.8 (8.0 in the gen 3 and super 6), untill proven otherwise
