Bring a scale to your parts house & pull back a boot. Eberg used to sell them for $35 to your door iirc (for a pair) which was a real nice deal & they were good American made ones. You might get ahold of him. A prop valve in the rear line may be an option live every 24 hour block of time like it's your last day on earth
