IHI Aftermarket Hydraulic Return Filter

I am replacing all the fluids on my "new to me" 2007 IHI 35N-2. I was able to cross all the filters except the hydraulic return filter to ones available at the auto shops. At $83 from IHI, I would really like to find a generic replacement for this as well. Anybody know of a second source or perhaps another mini-ex that uses the same one?

Thanks.
