As part of my 4.2 Sahara cleanup I ordered a complete set of radiator and heater hoses. FWIW, here are the Gates Part numbers, got them all off Amazon for almost half price over local shops. These numbers are good for '87-'90 you may want to double check them for '91 and up
Lower Radiator #20559
Upper Radiator #20793
Large heater hose #28479
(Heater to t-stat housing)
Small heater hose #18909
(Heater to manifold)
T-Stat to Manifold #21832
(Bypass Hose)
