Me too.
My notes indicate that the Four Seasons 74848 is suitable, but it might now be discontinued.
I think I may have used a Four Seasons 74648, and that one is brass, not plastic like the '848.
If I had it to do over again, I would probably install a cable-controlled bypass-style heat control valve somewhere down in the doghouse as that might keep the heater core a little cooler during the summer months.
