Welcome Ozzy. That's a tough way to learn about the LH threads for a wheel stud. When I work on any Mopar 1970 or before, I have learned to check the LH studs before removing the wheel. Typically, the original studs would have a L or an R stamped on the end of the stud. Many of the LH ones have been changed, but not all. I hope you find some, otherwise, change them to RH. ALso, if you keep the LH studs, let the shop replacing your tires know of the studs or they may do the same thing you did.
