A couple of things...

I've got a couple of battery trays for sale, wire-wheeled, rust converted, galvanizing coating and satin black. One has heavy acne,
the other pretty clear, just minor spotting.
$30 plus shipping for the pimply one, $35 plus shipping for the clear one.
Also have 3 rear wiper motor covers, one burgundy, one light tan and one dark tan. $40 each plus shipping.

I take Paypal, friends and family. PM for details. Thanks.

that's a fair price - i recently did my battery tray like that and it was a lot of work - did a por15? first, wire wheel, dremel, paint, etc... had to get some new hardware... mine was in bad shape - like your 'acne' one, but now i'd expect it to be good to go for a good long time.
