Iím sorry I can be of additional service at this time; as, I have not been able to get in touch with the vendor regarding your question. I believe you are inquiring about item #43269, 2001-04 Radar Detector Mounting Bracket. I do not have any first hand experience with the compatibility of the Bel Rx65 and this product. The vendor states that it is compatible with Bel products. So, you might want to see if all Bel products mount in a similar fashion. If this is the case, then item #43269 will probably work out in your favor.
