Will a GN Rear Bolt into an '84 Bonneville?

[BONNEVILLEG]

I want to upgrade the engine and know I'll grenande the 7.5 posi at some point and I'd like to bolt an 8.5 GN rear in its place. Is this a bolt-in?

Yes, I think all 78-87 G-bodys are the same.

Thanks!

You'll have to shorten the drive shaft about 1". Measure to be sure.
