Hi Ash welcome to the site. I also have a lend lease 1 1/2 to truck R/H drive and I live in Rockhampton QLD Australia I found my chassie number on the L/H side of chassie. Does your truck still have the 3 blackout driving lights. your truck sounds like most things are similar to mine. Are you in Australia???
Cheers Justin
