I don't think you will have a tire fitment issue unless we have crazy different backspacing. I have the same car, and I'm running 215/65-15 on the front with 245/60-15 on the rear. I have no rubbing issues. I did originally, but that was due to tired springs in the back and lowered front. I added helper springs in the back and cranked up the t-bars and now all is well.
I swapped out to RH studs in the rear (fronts will change to RH when I put the KH discs on). As moparmat2000 says above, I got them from Rock. They have a zillion kinds but I found the correct ones. If you need it I think I have the part number somewhere I can dig up.
Also, if no one told you, the front studs are swaged into the drum. You have to remove the swage before removing the stud or you will ruin the drum. My rear studs went out and back in easy-peasy using a HF floor press.
