i believe the answer to your question depends on the setup of your car...
though i haven't had experience with the "wilwood" brand, the replacement brake lines typically follow the same routing as the stock brake lines. in the case of the products you are considering, "wilwood engineering" does not manufacture a specific brake line kit for the solara; thus, it would be necessary for you to measure the distance (including some angles) needed to custom cut them and ship to you. i'm inferring that the "flexlines" described in the wilwood products mean you'll be able to make some minor modifications to the lines yourself (as is the case with most brake lines). if you are lowered, you'll most likely have to modify attachments brackets for the strut. you should make sure that the lines are not touching any part of the suspension or drive train. in addition, if you have disc brakes on both front & rear, then the distances for them should be the same...
secondly, i wouldn't order from andy's auto sport... and i am only saying this from several first-hand experiences that have been nothing short of a nightmare... i would also recommend getting rotora's brake lines instead (you'll be able to find new ones on ebay shipped for ~$25-30)... those are the ones that came with my big brake kit

finally, to answer your question on which on to get, i believe mine was similar to the last one on the first page (19 - f/m)... anywayz, good luck!
