79' Cutlass - 373 Gears

[Mooch]

I have a 79' Cutlass Supreme
I have a Chev 355 - 400hp/400tq
Im looking to put 373 posi in the rear end.
What whole rear end will bolt up to it and out of what make and year.
And is 373 the best option to use in my Olds.

Thanks

Eric

I think an 85,6,7 MCSS will have a drop in drum to drum rear. Sometimes a salvage yards computer search can locate one. Best is relative to your combo goals and existing transmission.
