Hi Steve,
None of my ID-1 radios came with a mobile bracket for the main unit.? Perhaps you could
measure the bracket you do have and let us know.
Doing some research, the ID-1 user manual lists an optional mobile mounting bracket
as MB-17A.?? The Icom UK site:
shows it is for several radios including the IC-2100H and IC-2200H.? Unfortunately, it's a quick
release bracket, and probably no longer available.?? There is one for sale on QTH asking $35.00
Looking at Universal Radio site information for Discontinued models of Icom,
it shows that MB-17A for the IC-2100H and IC-2200H, but also shows a bracket MB-28H.
Width and Height of the two models is the same of 140 X 40 mm, but the depth is different.?
The IC-2300H is also 140 X 40 mm, but different depth.? ID-800H is also 140 X 40 mm.
The Icom ID-1 User manual shows the dimensions of 141 X 40 mm.??
So the MB-28H or a mobile mounting bracket from the listed mobile radios might work,
but is narrower by 1 mm it would seem.? Might be worth a try or fabricate one?
DX Engineering shows dimensions of the MB-28H bracket when looking at the pictures.

Of course, not in stock.
HRO shows in stock in Sacramento, CA for $29.95
It says "Fits radio Width of 141mm (5.5") screw spacing 50mm (2.0")".
So, maybe the Icom MB-28H would work for you.
Also, the IC-2100H service manual lists part numbers for
the mounting bracket and various screws.

Perhaps a call to Icom America Parts to see if brackets are available?
