I used to own a 48 Stylemaster and will keep this in mind. I don't know for sure but #3 is not a valid paint code. Most utes were beige or cream though there were black, dark grey and light green. Has the previous owner managed to get rid of every trace of original paint? 121 as a trim is most probably brown leather facing on seat and vyanide on sides/ back and door trims. Ultimately you have to do some of your own research and find something that suits you. Of course they also used the same colours on early Holdens so if you go to GM Day you can have a look and see what others have. Ultimately even if you do track down the original colours you won't be able to get the correct trim, just something similar. Likewise with the paint. Even if you find the formula it will be cellulose nitrate which you can't get. As I said I will keep this in mind. My 48 was pale green with a tan interior and it looked great though I had to sell it; too many cars.
