Default 73 rear end in 67?

Short version.

Found 73 mustang grande rear in for super cheap.

I know it's a little bit longer, besides from that will bolt right up? It is a 8 inch rear.

It will bolt into the '67 but what are your plans for the extra length? I believe all Mustangs from 1965-1973 have the same spring pad spacing on the axle assemblies, so any of them will bolt up. The Granada, Fairmont, Versailles, family is also similar.
Best,
Al

65-66 are shorter and something about the u bolt is different.

But I'm looking to run late model rims and this keeps me from running spacers. But even then I'd be fine with it. It's a super cheap complete rear end. As long as it bolts up without me needing to weld crap in happy.

it be clear, the spring perches are in the same place and the rear will simply bolt in without heavy mods?

The axle tubes are a little bit larger at the spring perches so it may require larger u-bolts and some modification to the plates.

Fairmont is a Fox chassis with rear coil springs. Perhaps you meant Monarch (same as 75-80 Granada).

71-73 Mustang (61.25) are 2 inches wider than a '67-70 (59.25"). That would leave you having to adjust via wheel backspacing for a proper fit.
