19j and 200 tdi use the same mounts but when fitting a 300 tdi the drivers side mount is in the wrong place so its a case of cutting the old mount off and re welding or as ive recently found out you can fabricate a mount that uses the holes in the 300 block and the existing chassis mount
Im looking into this option for my series conversion as i dont want to weld my galv chassis and known good 200s are thin on the ground
