Jsalchenberg We used napco for spray trucks on corn and beans,really good in the mud. That was in "73,I'm afraid your in for it on your front end part though. However there are napgo guys out there,once broke the short front axle, a sharp local machinist made us one that was a perfect fit !! With 500 gallons of spray and 40 foot booms on you could get thru a fairly big wet place if you didn't let out of it !! Pretty good fun if it hadn't been so seriously important to get thru it with your expensive and important load !! Tough looking truck !!
