Wanted: Front Lap Belts

[gzig5]

I need a set of front lap belts that will fit in my 73 Cuda.  I have the shoulder belts and if yours will work with them, so much the better but not required.
Two criteria... must be functional and must be CHEAP.  I don't care what color they are (black if I had a choice) just need to be safe and functional.  I can get a nice new aftermarket set for $75 per side including improved shoulder belts but if I don't have to spend that cash at this time it can be put towards other parts.  Car isn't going to be driven much in the near term but if I do take it out for a shakedown drive, I need belts.
