FSA Gravity Crank w/ Sun Ringle Pedals and MRP chain guide

I have an older FSA crank that have Sun Ringle platform pedals on, which will NOT come off, believe me I tried. I also have an MRP chain guide that only has one roller with it. The crank arms are 170mm, and the chain ring is a 36T. There will be full hardware with it too to attach the ring and the bash-guard. I am not too sure what the actual value is when I got them, but $50 sounds about right, but if you give me an offer I will tell you if its good. I will also give you a good price on shipping!
Cheers
