    What rear ends will fit an 88 Colony park?
    I want to go with the crownvic Police interceptor rear due to it having posi and 3.55 gearing. But im not sure if itll bolt up without a hitch.

    I'm not sure about axle shafts, which is a consideration, but any 8.8" diff unit will fit a Panther 8.8" axle housing. What gearing you want depends on what you want to do with your car. On the one hand, towing and hauling could use a 1/2 ton truck 4.10 diff for real pulling power but totally killing mileage, as a 3.55 does; but if you aren't towing, and still want giddy up and go, a 3.27 ratio (most of those came with an LS) would suffice. Other than that, there's the 3.08 and 2.74 ratios for faaaassst running.

    A 3.27 would probably be the best option, since ill be running a m5r2 which already has a balls deep 1st. Do you know which models which came with those?

    Panthers, mostly, so start looking. Just asking: do you know how to read axle tags? They'll tell you the ratio, and whether it has a limited-slip unit.

    Some early '80s F100/F150 trucks with the 3.8L V6 also have that ratio.

    Yeah, theyre usually pretty straight forward, its a lot easier to read with the trucks.ill start looking out for those at the yards
