I had my driveline done by Driveline service in stockton and I liked the customer service. They are pretty good guys and bolth of them had 4x4, They lenghtened my rear insted of shortened it, an easy mistake to make. I went to pick it up at about 12:30 noticed the problem, they fixed it for me and I came and picked it up about 4:30 that afternoon. And I'm also runnin one of there ultimate slip yokes up front, there awsome.
