Auslowe stocks some parts separately that are still good for American super liners. Mk1 head lights, Crossmembers and camel back suspensions, E9 V8 etc.. The italeri kit can be converted reasonably well to an American spec by narrowing the cab and using an amt cruiseliner front end for the mk1 or using the dm600 front end for the mk2. In Australia we kept the r series from rails up until the year and 1999/2000. There was an article about converting the italeri kit to make it acurate, I think it was in scale auto. Hope this helps.
