I agree, I think 81-083 is definitely our best match. That was the first part to come to mind when I looked at your photos, even before I read your inquiry. Since the dimensions all seem to match up then I think this is a good pick. The only thing that I'm wary about is that your housing has a slightly different design, but since everything else so closely aligns we can probably chalk that up to yours being an older version.

I'm afraid I can't calculate shipping cost off the top of my head, since we offer a couple different delivery options, but it is calculated for you automatically before your order is finalized (in case you wanted to make any changes).
