seat belts

Cuda 69,
Hope this doesn't come off as being nosy, but what was the price (genral, aound?)to get the belts restored. I looked at another site and they didn't list prices but they had a set of restored Charger belts for sale for $1,200, which may me afraid to even inquire with them. I will be hauling precious cargo once I get my Dart back together and would either like to replace(with something that looks somewhat correct)or have my original crusty faded belts restored.
