1972 Chevy Custom 10 - value??

[impaaala]

Hello,
I need a little help. My mom recently passed away and my brother and I were left with their 1972 Chevy Custom 10 pick up, which they bought brand new. It is in fantastic shape, it was restored in the early 90's, the engine was completely rebuilt as well. It is Green and White two tone. The original wooded bed started to rot so my Dad rebuilt it with a clear finished Oak planks he bought as a re-build kit with stainless steel strips which looks really fantastic. The interior is completely original, with only a little dry rot on the top back corner of the passenger side. The gas tank was also replaced, but we have the original tank. Can anyone give me an idea of how much this is worth? I can get some pictures if that will help or if anyone is interested. Thanks for any help that anyone can generously provide. Ernest
