Help!! In Need of A Bench Seat

[Snifflez]

I just started restoring a 67 Chevy C10. It has bucket seats out of a modern impala and they don't fit in the truck and are really ugly. I want to install bench seat but I can't seem to find any used springs online and there are not a lot of aftermarket bench seats. LMC has a couple of seat kits that are decently priced but I really don't want to go through the work of putting one together. So my question is it more cost effective to have an upholstery shop build me a seat from the ground up, try to find used springs or just buy a seat/kit online.
