wheels after disc conversion

I am converting 65 front to disc with 77 donor parts.
I will also be replacing wheels as well soon.
i have new 15 inch tires, so would like to stay with 15 rims, so my question is this, cause I cant find in my search
What offset or backspacing do I need to stay within for the new wheels
LMC has vision wheels with 0 offset and if that is the case, there are limited options with 0 offset
I have searched on different wheel sites for wheels that will fit 77 truck and get different options
I am new to the wheel thing and have seen lots of threads about disc conversion, so anyone with any insight would be greatly appreciated

What size 15 inch tires? That is going to determine what rim width you use and the rim width will dictate how much backspacing you need to stay under the fender and not rub the radius arm at full lock on the steering. I have 235-60-17"s with 4.5 inch backspacing and everything clears fine. Also some aluminum wheels are quite thick and 15 inch ones might not clear the caliper bolt if the backspacing is over 3 inches, steel wheels should clear fine.
