Back Spacing

[shoram50]

Anybody know what the backspacing is on rims for a 84 ram50,
have an opportunity to get 4 15X8 6/5.5 custom wheels for a hundred bucks,
just wondering if they would fit with 215/60/15 tires... truck is bone stock

Old thread but.. did you ever go through with it? I have 15x8s with 3.75" backspacing and -6mm offset. I was wondering if I'd run into problems with a 205/70
