As far as I know, herringbone headlining vinyl is available in a few colours. Some big motor trimming suppliers are Daleys, Radins and Paskal. If you haven't fitted one before I suggest you get it professionally done. It's a big job and not a good one to cut your teeth on. If you want reproduction door trims, there are only a few doing it. I can recommend Winner products in SA. Not cheap but very well made. Carpets are pretty much the same colours across all suppliers. You will want a front carpet and a rear (half) carpet for vans and utes. Original was loop pile, not cut. Door trims and moulded carpets most people can fit themselves. Moulded carpets are designed with allowances for a layer of under felt for a good fit. I'm not sure if a "buckskin" colour exists but variances of beige will be few so pick one that's close. Hope this helps
