My issue with the RA-140 was the housing body itself. A bit of material needed to be removed from the upper left corner / upper left side area. Though it had fit with no issue, evidently there was enough bind on the assembly to cause a functionality problem. I was really PO'd why RA chose not to mention that in their literature, descriptions, etc; unless of course you contacted them and they asked what brand and model you had. After that, they literally couldn't give me any of their products.
