I just bought a complete set of uppers and lowers for my car from Pole Position and am thrilled with what I got. The complete package was around $750, but I also got a kit for doing complete alignment from them as well. The fellow there was extremely helpful and I called about 6 or 7 times to get everything right. He didn't get upset at all!lol
The units come complete with all new ball joints and are ready to go..
Take a peek....they're beautifully made.. Just look in their main menu for Mustang ll suspension parts.
