Alignment issues? Aftermarket?

2014 W212 E63S Wagon, Facelift
Recently I replaced the 'Cross Strut' component on my wagon on the driver side as they fail. After replacing, it was obvious my alignment was completely fubar. I took it to a Firestone that i have a hookup at (Free) and they were able to get the car CLOSE but not entirely there...
Now I called up the dealer, and got a price on the alignment, and of course its made out of magical German pixi dust that only their knuckle draggers can perform so it costs an absurd cost for an alignment. I digress. Is there a good alignment aftermarket kit I can get that will allow a normal shop like, say, a firestone that i can get service at for free, and even if i can't they offer lifetime alignments for ~190, and the roads in the north east may as well be the lunar landing site, so I'll need another.
Thanks!




Other option is kmac which worked great on my e55
