My truck is a 55.2, Task Force rig. Also yes "1 ton" was a typo, been using the phone and didn't catch that. I did re-read the post you guys mentioned. The first time around I did not catch where someone talked about the front cylinders being discontinued. Will start to pull some stuff apart and see what my casting numbers are.

Thanks
