Looked around for something on this and could find nothing, so here it goes:
I have a 1953 GMC 150. I am converting to 1/2T running gear with a 10-bolt rear end and leaving the front end with I-beam (but changing to 1/2T to gain the disc conversion/5-lug hub). I was wondering what the widest wheel is that I can fit in the rear without tubbing the bed? I know backspacing has a play in this (along with the width if the upgraded rear end, although the tire will eventually hit the bedside..). I will either run 15 or 16" wheels and 60/70/75 series tires (not sure yet, as I also know tire series plays into the equation). Just curious on what folks have gone with that works without modification.
This is my first post. My project basically consists of the above truck, a chevy 230 (might be a 250, will not know until I tear the head off), which I will need to rebuild and install new frame mounts, a 4-speed Saginaw (of which I will remove the original crossmember and install an aftermarket tail mount). I will consider shortening the frame as the very last effort, as the bedsides can use some work, and I do like the shortbed, we'll see....
This is a great forum, and look forward to being a part of it.
