Rallye Wheels - Help Needed

SBP Rallye wheels were all 14 X 5-1/2 from the factory. No other sizes. The aftermarket has made other sizes available but it's almost a sure thing yours are factory. Yes, the caps have retention screws accessible with the wheel off the car.

Lug sizes are only 7/16"-20 so they snap off easier than the more common Mopar size 1/2"-20. As already mentioned, the left hand side are opposite thread. CW to remove.

You have 20 nuts around that car. I'd start in the rear because those studs are easier to replace if you break one off. A good impact wrench can easily snap it. I'd probably start with a long breaker or cheater bar with a 6 point socket. A 1/2" ratchet with a cheater bar would be good because once you get one started, continue until it is all the way off. It will heat up from the friction and stopping will cool it down locking it on the stud even tighter. Your goal is to get one off to analyze what is happening. It very well could be double-seated on the end of the stud and at the wheel. Penetrating oil may help a little, couldn't hurt anything on the wheel so no worries.
