Question about 23-178

I think the 23-178 can still work for you. The offset is a little weird on this one. It comes down to where the dimension is taken. The full bottom of the offset is 1-1/2", but if you look at the back view of the roller you can see that the bracket is indented forward a little. That brings it up to about 1-3/8". Would this still work for you? I'm afraid I couldn't find anything closer.
