needing 360 enine mount brackets, can anyone help?

hi, doing an engine swap in a 68 Satellite , from a 273 to a 360. the engine came from a low mileage motor home . we have the special b&m flex plate but can't use any of the block brackets we currently have to mount the insulators to the frame. not positive what application to ask for to fit this setup, hopefully a mopar enthusiast can help, good chance to pick up some extra cash for yourself. able to pay thru paypal for a quick and easy transaction.
thanks,
scott
