1969 C-10 opinions (restore or not)

[Hobbs81]

So I was lucky enough to find a stone stock, totally rust free 69 C-10 stepside. My initial plan was to resto-mod (big block, fun stuff), but I have since discovered that the engine / trans are matching number and all options are still present, with nothing extra added. (except the hideous huge mirrors and the wheels are incorrect.) It is a very low option truck, but does have well functioning factory AC, and the gauge package, radio. 307 V8 w/ TH350. Two knowledgeable body work peeps have inspected and say the paint is original. Even has the original wood in the bed, in good condition.

As I still want a resto-mod truck, but am not willing to chop up this survivor, I'm trying to decide whether doing a minor engine restoration (stop the leaks) and sell it as is, or do a complete factory restoration. Basically which would yield more return on value? The labor cost of the paint and body work need not be considered, I have that covered separately.

Thanks
