I have three new battery tray supports. Two are new and one is a used one that is sand blasted clean. Do not know the manufacturer but I suspect one is AA as it is missing the nut that takes the battery clamp hold down bolt. They sell for about $60 new.
Asking $40 each for the two new ones shipped.
$30 each for the used one shipped.
The used a tray and support has some surface rust but is solid. Can get it sand blasted so it will be ready for installation. Asking $50 shipped for it.
