Will a 1969 split bench seat cover fit on a 1966
I've got a 1967 Impala that someone stuck some 80s cloth buckets in. I`m looking to go back to a bench seat. My rear seat is in great condition and looks very similar to the 1969 Impala seat covers. To save some money I'd like to leave my rear seat as is and match the front to it. I found a 1966 Impala bench seat frame near by and was wondering if the 1969 seat cover would fit it? Also in case I can't get that 66 frame are there any other years that a 1969 cover would fit? Are they pretty universal or will they only fit the year it was intended for?
