where can I find this

Find the Detroit # for your original upholstery . Resto shops have the Detroit book. Molar assigned codes for each type and color.once you have this# you can order from SMS the correct vinyl . Although matching 40 yr old front to rear is likely not possible.i tried and had to do both. shame too as I only needed small patch on drivers seat! Good luck! You should be able to get but may take some time as they do not make small runs.
