if you want to make them , depending on what engine are you using is what design of motor mounts you need , 24 v and common rail have more holes in the block and you can get away with 2 right common rail mounts and brackets , the metal frabrication part is very easy, just a plate and 2 ears , for the 12 valve you can use peterbilt cab mounts is what ford cummins uses , theyre 25 dlls a pair on ebay , and to make them you just need a 3x3 angle iron the rest is easy , will post some pics. its really not much to it.
