Dan Gurney specials were produced for the 1967 and 1968 model years only. They were promoted by Dan Gurney who signed a sponsorship deal with Mercury for the 1967 Trans Am racing season. The DGS option included a chrome engine dress-up kit, “turbine wheel covers” and a sticker on the rear passenger (needs to be confirmed it was passenger side please) side window. The chrome engine dress up kit consisted of a chrome air cleaner lid, dipstick and valve covers.
