I have a 68 dart that is mini tubbed, and leafs relocated. I currently have Crager SS 15x8 & 15x7... I bought them off craigslist NIB which they are but I dont like the way they fit on my car... a lil to close to the fender lip for me. I still have SBP but I really like these centerlines but sont know the correct offset.

You could buy something like (or make somthing) this and simulate tire and rim fitment. I fit a 9" wide rim on my 65 Cuda with stock wheel wells, so I would think you might be able to go to a 10 rim with the right back space.

on my 72 i have 10 in. welds with 4.5 backspacing and i had to roll the fender lip. i should have used 5 in. b/s oh and i also have the mp spring relocation kit
 
which back spacing will work 5" or 3 3/8" or 6 1/2" or 4 "1/2 or work? I saw a dart w/those on there toby but he didn't know what the back spacing was....

I really like these.. they come in 15x10 w/a 5" back spacing as well......u think that will work?
 
With a stock rear you can run a 15X10 with a 7.5" backspacing. Center line also makes a 15X10.5" with 7.25" back spacing which should work.
 
maybe the wheels we had on the 70 were 15/10s,i but i know they had 7.5 or so backspacing for sure.the were close to the fender lips,but i think that was because of the tires we were using.It was over 10 years ago.I wasnt sure they were still making these in small bolt that wide.
 
Center line has a 15X9 with a 7.25" back spacing also. The centerlines you can get in small bolt pattern still.
