I believe they should be 5’7″, which is the same as an M7, but it’s hard to get an impression without a side-on photo of the model. If it’s the original K’s chassis it should be OK but sometimes if you fit a better etched chassis to a cast kit it can end up too high as the chassis doesn’t take account of the thick white metal running plate. Buffer height compared to something else that you know is correct is the best bench mark.
