DONT GET THEM.
They have sold a few others like this on ebay, often for a few bucks... like 15-20.. never this high. But it was about a year ago that I saw them.
also note they do NOT come with railes. So now you will have to contact T&D and ask for the railes that these mount into, and sonsidering its R&D, whats the chance they are going to be happy to sell you a set? and then ask how much !
Honestly, NOT worth the risk, I bought a set from mike, he does a GREAT price on them, and you'll be very happy.
Dont take the risk on USED R&D parts... is the risk to your healthy motor worth saving a few hundred bucks? I think not !!
Let this one go, but good work on finding an ALMOST good find.

Ps. I may be an ***, but one thing is for sure, I always watch out for the family, even if I am rude to them !!
