Also they say that the REAR FOG will not work with these tails. Anyone have any insight as to why they wouldn't?

Want to try them out but their return policy sort of sucks and seems like you'll get screwed if you don't decide to keep them.
Return policy details::::: Any Products returned for a refund or exchange must be returned within 14 days of purchase. This includes products deemed unsatisfactory (subject to our approval), defective or damaged, we advise all customers to inspect their order(s) as soon as possible from receiving them and to notify us of any issues/problems. Anything over the 14 day return period, we reserve the right not to accept returns. For any return, you must eBay message (NOT via email) our Mars Performance staff and explain in detail, the reason for the return (attach any pictures if necessary/needed to show the issue/query, via the "Attach photos" TAB within eBay messages). In some cases, the pictures sent through eBay messages are not very clear, so we may advise an email to re-send them for further assessment. The next stage (if agreed by us to continue with a return) will be to obtain from us, a Return Merchandise Authority Number (RMA). We will then eBay message your (RMA) number with our return address for the item(s) to be returned (in its original packaging and in a resale-able condition) with our return conditions. You should also ensure that the contents are safely packed (as they were originally with original packaging) and/or add any extra packaging you deem necessary to prevent any damage to the product(s) once we receive it. We reserve the right to not refund your order and if necessary return your order back to you at your cost for delivery, if we find that your order is returned to us damaged/or not in a (resale-able) condition or WITHOUT an RMA number. We may in some cases offer a partial refund that we deem is appropriate depending on the condition of the returned item(s). We will contact you once your return arrives at our Warehouse and advise of any issues, or refund (if applicable). All returned product(s) are to be posted back to Mars Performance by Australia Post (via regular parcel post with tracking) or depending on the product, a carrier that is suitable for the product you are returning. You MUST contact Mars Performance before any item(s) are returned/posted back to us, so that we may choose an appropriate carrier and service, where Mars Performance is responsible to pay for return postage costs. Any items that are returned/posted back to Mars Performance without our consent and where the buyer has made their own choice of carrier/service, Mars Performance will not be liable to pay the return postage. If the buyer also attempts to return/post any products back to us without any tracking and without our consent, and the item is lost/missing during transit, we will not be responsible, and the buyer shall not receive a refund for any such return, regardless for the reason of return. Any item(s) that are to be returned back to us, we STRONGLY advise that they be insured for your protection and peace of mind if any issues should occur with your return. The return shipping cost will be at your expense, (except for orders that have been dispatched incorrectly by us), in these matters, we will bare the cost's for the return postage. We reserve the right to investigate, and test the Products (if at all possible) to establish the reason for the Products being defective. Defective Products will be replaced or refunded within 14 days of receipt of the returned Products. For Products that are deemed not defective or returned due to incorrect ordering by the buyer, you will be charged a restocking fee equal to your original orders shipping (our cost to post the item(s) to you) & handling cost, plus 15% of that cost. You must include with your exchange/return your Return (RMA) or we will not process your return. Products, defective or not, that have been installed, used or operated or have been altered/modification in any way, (including products such as wheels fitted with tyres and not tested for fitment, including products that require painting, which are painted by the buyer, but not tested for fitment purposes prior to painting) subject to misuse are NOT eligible for a refund or exchange.
