I just picked up a MOPAR donut tire/wheel to use as a spare. With it came a wheel spacer for use should I need to use it on the front of my SRT. When I mount it on the back of the wheel the spacer doesn't fit flush. It's got about 1/8" of slack/wobble. Referencing the second pic note the A, B and C. It appears the portion of the lug between "A" and "B" bottoms out on the spacer before "C" seats on the wheel. Anyone have any advice? Thanks.
