The SN95 (94-04?) lower control arms are slightly longer than the Fox models, so FFR has provided a pair of frame mounting holes to accomodate either model and retain the same track width. I don't know that there is much to recommend one over the other.
I ran front lower control arms from a 1995 GT while still in go-kart form but bought a set of FFR tubular LCAs off the classifieds. I did have some clearance issues around the steering rack tie-rod ends and the top surface of the 95 LCAs at full droop, but most told me that since it was only at extreme droop (car on jackstands) it wasn't likely to be an issue with the car on the road. They can also peel weights off the inside edge of your wheels at full steering lock, so you need to watch for that and grind clearance as required. There's lots of meat on them strengthwise, so I wouldn't be concerned if you have to shave them a bit.
If it were me, I would save my dollars for the tubular LCAs. Most true donor stuff is pretty high mileage and if you add up the cost of replacing ball joints and bushings, you will be most of the way to buying new tubular LCAs.
I forgot to add that with the SN95 LCAs you need to drill the coil-over mounting hole (it's existing in the Fox models). You need to measure carefully and favor the rear edge of the spring pocket slightly so you don't end up mounting the bottom of the shock too far forward where the spring will touch the tie rod ends when the wheel is at full steering lock. You can ask how I know this but I may refuse to answer
