Original radiator hose worked fine on mine. No need to change. 4 years and no leaks, seepage, or splits. Never a temp over 173*.Skip the fbody as the the lower radiator hose on the pass tank is different. Go with a 87 regal 307 radiator cools just as well as the fbody on.
You will either have to remove oil cooler adalter or run a aux engine oil cooler.
The all alum radiator options with oil cooler are Alradco and GN1 performance.
If you want to pay for a OEM replacement then they are out there to.
