Wheel spacers are easy, if you can change a tire, you can do wheel spacers. Just make sure you get hub centric spacers so the load is on the hub itself and not the lugs. The 20+ explorers use a 5 x 4.5" or 114.3 mm bolt pattern with 14mm wheel studs and a 70.5 mm hub bore. BTW all mustangs from 1994 to present use the same and the early explorers up to 2010 did too. The 11-19 explorers had a smaller 63.4mm hub because they were fwd based platform. The only difference is the mustangs used a 1/2-20 wheel stud up to 2014, and the explorers up to 2019.
