I've been told that vl stock diff gears are 3.45s and will fit into a vp diff. But my vp has IRS. Will the 3.45s fit IRS diffs? I think my Calais has LSD but now I'm not so sure, if it's LSD will the 3.45s still fit?
I've got them in mine (VP IRS), so yes(yes to everything you asked)
Sweet, thanks greenfoam. I've sent you a email asking about a tune for a manual vp v6. Hoe much are yours?
vl turbo gears are 3.45, rest are 3.08 iirc
