If you have access to a Trooper with the AR5 I would go that route. Everything will bolt in place. I would also suggest getting the fuel line from the Trooper otherwise you will have to bend the lines around the tranny by hand. the Rodeo most likely has the MUA5 speed trans. You will probably have to have your drive shafts modified to accommodate the different lengths of the transmission. The bolt patterns are the same between the 3.2 and 3.5 engines. I have installed an AR5 in a 95 Rodeo with a 3.2.
