"you are only dropping 45 VDC across the resistor, so its not a concern."
Except that the OP said the resistor has more than 400V on it. Looks like it's safe though; the datasheet says the RH050 has a 2,000 Vrms dielectric strength. Given that it's only dissipating 8W, your idea of bolting it to the chassis seems like a good solution.
