When I replaced the rear heater core and valve I got the parts from Van Cafe.  The valve was a newly created all metal version and really nice.  It has been about 5 years and all is well.

this is a job I did on my own with help from this list.

any advice on where to get the parts for this job?  I will need both the
heater core and the valve.  Both are leaking.  Are there certain brands
that are better than others?

Thanks!
