tire width under stock wheel wells

67 - Wich kit did you use to move the springs in. I just mounted up my Hoosier quick time 325-50-15s. Right now I cant bolt them up becuase I havent moved the springs in but I'm 99% sure they are goig to fit without mini tubbing it so I can keep the back seat. They are on a 15X8.5" rim with 4-7/8" backspacing.
