15x8 6 lug steel wheel question

[jmking9]

Im looking for 6 lug 15x8 steel wheels for a 72 4x4 blazer I'll be starting on soon. I know Wheel Vintiques makes them, but they only come in 4.25" backspacing from what I can tell. I have read that 3.75" is the limit to clear the tie rod. I believe that to be accurate because the 6 lug rallies that are currently on it are relatively close with their 3.625" bs. There are the CUCV wheels off of the military blazers that would work, but seem to be impossible to find. So, is there anyone with personal experience on if a 4.25 bs will clear the tie rods on a stock 72 4wd? I'm open to other suggestions also, so if you have one, bring it on. Thanks in advance.
