working 120mph speedometer for 74 duster

I'm looking for a working, nice condition 120mph square speedometer that would work in a 1974 duster

The broken one I pulled out was
PN# 3592183

The local speed shop said $150 to fix it, and that seems really steep to me since the face is scratched up. I'm looking for a decent one that is know to work which you could sell me around the $75 range.

I know there are a couple on ebay for cheaper, but they look pretty gnarled up.

Thanks, I live in Tucson AZ. PM me if you got what I need !

Trevor.
