1974 Scamp What Wheel/tire size question...15x8 b/s?

I have a 72 swinger,I'm running 15x8 on rear with M/T sportsman S/R LT 26x10r 15.BS is 4.5 no rubbing on springs or wheel lips,although wheel lips have been cut.On the front running 15 x 6 3.75 BS w/205/65/15.It is pretty close to wheel lips though.I'd take pics but car still up on jack stands,torque converter crapped out.Luckily I live 40 mins from summit went and bought a rim stuck in on car w/out tire so I could measure,you probably know but once tire mounted rim/tire yours. If your going w/wheel vintiques 63 and dog dishes you have to grind the grooves in the knubs that hold cap on deeper or else you'll have problem with caps staying on.Unless they"ve fixed their dies since mine were made.
X2 for measuring,
