Paul,
You should be aware that 73s are kind of special so be very careful and have the early manual downloaded. There were supposed to be some dealer mods to the front end structure that you should look for and a recall on the rear drums. No telling what POs did along the way.
And I forgot a part of my usual welcome.
As this community is so much like that of the watermen that are my world, I always like to add this to the welcome. It is much like you might be welcomed in that world. So,
May the Good Lord bless this coach and all those that set forth withing her.
Welcome Paul,
Matt
