N.O.S. 1970 Chevelle parts

[Big Block Bill]

Good Morning Everyone,

I have available to me an N.O.S. rear bumper & pad for my LS-6. In the package of parts I am looking to buy, there is a set of N.O.S. GM 8735905 & 8735906 1970 Chevelle quarter panels along with both N.O.S. GM outer wheel houses (I don't have the part #s, but I know they are real GM). All the parts were purchased in the late 1970's from a local Chevrolet dealer. I do not know what their current values are. Does anyone have a clue in Todays market what all these parts are worth? I would appreciate any input.

Thanks,
Bill Pankiw
