Spring offset and rim and tire size 68 Barracuda for thos who have done it

Just crawled out from under my 68 notch. My stock location stock drivers side front spring hanger measures .698 from the frame inner wall to the bracket outer wall...the other side is .708 pretty much looks pretty close enough to 3/4 to me. I'll have it on a lift at work this Saturday, clean up the grime and take a better measurement with my planer gauge this time. 295/15's seem quite large after looking at what I have left now with stock spring location... if I could get an 11 inch patch, that would work for me...
