Very interesting! Especially the antenna mounts - which is honestly what caught my eye first. Thinking Ham radio whips
Here is the same eBay listing
but with US shipping.. not much, but slightly cheaper.
And this listing
is apparently someone who purchased it and is selling because it would not fit his 2009. Hmmm.. so these won't fit out trucks?
Also, just found it on AutoZone's
site for $145.99 with free shipping (to US addresses) and they're running a special right now. Every order over $100 will get a free $25 AutoZone gift card using code BIG25.. thus dropping the overall total spent to $125.99 (if you shop at AutoZone and will use the card).
I went through the checkout process:
Light Mount - $145.99
Tax - $8.69
UPS Ground Shipping - Free
Total Due - $154.68
If Summit Racing
has up to date info, then this mount will only fit up to 2006 Rams.
EDIT: (I know, I know..)
Just found this picture in Bing pictures but cannot locate the part on JC Whitney
