I forgot. I have these listed in other areas of ADV (w prices) but you're right. . . not in RM FM.
$30 for the fuel tanks (MSRP is $50)
$25 for the mounts.
$25 for the water tanks
Shipping for one set (Priority) is $12 for the lower 48.
I have 755 feedback via eBay @ 100% and my paypal address is confirmed. I've been a member of ADV for years, so this isn't spam
Sorry for the mistake. Drinks on me next time.
