Hi Gil, contacting them would definitely be best. They also offer the components to perform the install at home if you'd be open to that option, you could save some money for sure. I've purchased quite a few parts from them and I'm very happy with the service, quality, and price of their products. I have two 1963 Impalas, one is a hard top the other is a convertible SS. I also have a 1979 Malibu with hydraulics with many parts from Hoppo's. Good luck with your build, that's an awesome car that you have!!
You have to call them I don't work there
