Welcome. this isn't my era of Old's but if you drop on down to the vintage forum there is a group of guys that are dealing with these issues now.I believe the thread is Who owns a 47 -49 Old's or something like that they should steer you in the correct direction.

When you can post a few pictures of your ride, we love pictures....Lost in the fifties ...Tedd
