So, I've been looking around on the Australian Ebay and other google searches for a set of the proven 3.08's from older Holden vehicles.

Well, I stumbled across these https://www.summitracing.com/parts/spz-36346/overview/make/pontiac/model/gto/year/2004

The Brand is USA Standard Gear. The part number is:
883584363460

I hope you can leave the link up long enough for a few answers :(

Has ANYONE every heard of these?

I understand how tall these gears are but I'm more than willing to run them should they actually work considering I'm running a Twin Turbo car with a 3600 rpm stall and a TH400. This would give me soooo much more enjoyment. I imagine it's a typo or somethings wrong and they won't work.

If any of you know anything about this, please let me know!

Thanks,

No, those are for a different diff. Ours is a GM 7.75 (Spicer/Dana M80). I think Aus is the only place you're going to be able to pick up the taller stock ratio gear sets.

I forgot to mention, you CAN get 2.73 from Australian ebay and those ARE correct for our diffs.
