Hy blueck, firstly I do not know if Budd wheels were ever used on 1953 400 series GMC trucks. I'm pretty sure we could find some appropriate length studs if we looked for them, or you could shorten your existing studs, however the method of shortening is important as well as we don't want to put much heat into the stud in the process and mess with the studs temper. I know it is not a five minute job to change the studs, but that is what I would vote for. If you could remove at least one front and one rear stud and post the specifications here we could help you look for some appropriate studs. Hope that helps.
