Hello all. I am looking to get new wheels for the '49 and have been running the factory stock rims. I am pretty sure the backspace is 3.5" - looked for info online and can not locate 100% solid answer. This page give some specs ( http://chevy.oldcarmanualproject.com/chevyresto/5037.htm ) but not backspace. I need to have the same backspace on the rear for sure or the offset will interfere with the skirt (I tested a 4" backspace rim w/tire and it rubbed.. ) Looking at these: https://www.summitracing.com/parts/usw-655-5534 http://www.speedwaymotors.com/15x5-Inch-Steel-Smoothie-Wheel,81346.html Thanks in advance for the assistance.
Take your existing wheel and measure it's back spacing. http://www.jegs.com/images/wheelmeasureguide.pdf
