No one replied, I’ll jump in since I just did belts in my 46,
I looked around a lot and ended up buying from Julianos.
Why, many on this site have bought there, for me total package with hardware was most complete, products thought out and including everything prices were competitive. They have instructions pages you will want to review in any case.
Tying the center belt to the same mounts as the sides should be fine, but review how those mounts are backed up, standards have changed since the 60’s and if you don’t like what you see adding mounts is a easy task. We used to use large round washers, now we use curve edged rectanglular plates, standards do evolve.
Shoulder belt mounts are the task, look at youtube, brothers trucking has a video on a 60’s truck I believe, David Welsh? is pretty good, having said that I don’t know why folks feel the need to weld in the shoulder mount when rivets will hold that backing plate in place with no mess, either way it is just sheet metal you mount to, each his own…
(As a side note: on my 46 (which is a fully finished truck) I could install a 10x10” 16 ga roll curved plate behind the shoulder area sheet metal, secured it to structural members at both the belt line & door frame, then mounted a under floor sized bolt plate behind that), each his own…
