hi stevrolet46, welcome to the garage!! if you've got the original 46 radiator, prolly shouldn't have a pressure cap, cuz they didn't have - the 57 235 would've had a 7#, and if you've recored the rad or replaced it w/ new, then it prolly could handle 4# anyway - as far as hoses, use what ever fits between the 2
sounds like a truck I'd enjoy, got any pics of it up anyplace? we like pics!!
Bill
