GTR8000,
Good find. I see that item is on the
BCD396XT accessories page. I guess the OP needs to verify the compatibility just to make sure.
Cheers! Dave
No way to tell if the dimensions are the same from the picture.
One thing I do see is the one in the picture uses an actual machine screw to attach it to the radio housing while the original part was affixed to the 436 using a non-machined screw.
If the dimensions are the same and the hole in the available part is close, one could probably make this one work if you can't find a suitable mic hanger part from a Motorola mic.
Paying attention to the screw length is important so you don't drive it into the radio.
My 436 has a screw that more resembles the typical threads used for holding plastic cases together. Not sure if there is an official name for that type of thread and many are considered self tapping when used in plastics.
