Report Seat Belts. in 1963-64 Avanti Posted January 17, 2015 Hi all. Well I know it has been a while. But today we finally got around to fitting the seat belts to the rear seat of the Avanti and sure enough, just as you all said, the anchor points are there although after 53 years. the bolts refused to come out. had to drill them out and fit new bolts and nuts etc. As for the third anchor point, we ran the strap over the back of the seat through the hatch opening in the parcel shelf and down to a fixing through the side of the spare wheel well, which is very solid. So it works well. Little Hunter will have a safe ride at the Easter Studebaker National meet in Wagga Wagga, NSW. Thanks for your input. Dave.
