Help with part number

[240DRFT]

If anyone can help me find out what make/model/year these rails are from it'd be greatly appreciated. They came with a sparco seat i bought a while back, guy i bought them from didn't know what they were from either. Have a few part numbers but can't find anything myself....the right rail (one w/the handle) has 930826 on the outer rear, NA2 on the inner track, and NA02 on the top. The left rail has 930825, NA1, and NA01 on the same places. The side mounts are sparco, think they were purchased separately from the rails. Thanks for any help
