Andy,That front mounting plate can be a challenge. I wrapped duct tape around itself to it could stick to the top of the cap and the bracket while the nuts were started. You could probably duct tape the plate to the cap as well if needed. I thought the MK would match up by removing the right cover off of the MK to gain access to the MG pattern. It worked on my 80lb Fortrex, but it may not work on the larger units. Hope this helps. Carky
