Would you ever sell a copy of the program to cut out the plate? I'm a CNC machinist and have access to the tools and programming software to fab the part my self. I don't know if you would be comfortable with that?

You should consider making one for an 8.8 to utilize the readily available Explorer rearends. That would give the correct upper geometry or even raised an inch from stock.

Can the gov lock be replaced with a posi from a different 8.5 rear?.... like from a full size gm truck?
If you want to further bullet-proof your 8.5, order a posi from a 89-up truck - they got 30-spline axles and Moser makes axles shafts for GN upgrades. I found a 10-year-old new -in-box Eaton posi on Craigslist - it dropped in and these axles lines lined up perfectly.

Problem with the 8.8 is
1. They run 4.5 instead of 4.75 bolt circle
2. They are offset pinion and too wide, have to cut the axle down and get another shorter axle from an identical rear.

And the zr2 8.6 is plentiful, not as much as the 8.8 but quite a few out there.

I was more or less thinking a stock replacement. Did any GM vehicles come with a clutch style 30 spline 8.5?

The 90+ B body rear (mostly cop cars) had the clutch posi, BUT the 8.5 posi rears are a bit tough to find from my findings.

Yeah I completely understand, you should look at getting your idea pettented before a big corporation sees it and takes it for themselves.
