i just put a three point retractable belt in the 62. got it from dan's classic. it was 85 bucks and was simple to install. i found a install page for a company called juliano's and applied them to my own intall. a trick i figured out was to use some jb weld to connect the nut to the washer that was going into the body where the shoulder belt connected..... made it much easier. slid it into the body by taping it onto the end of a crowbar...
