1963 Impala 2dr

[PLATINUM6BBL]

I don't know if this the right section to ask this but here goes. I have a friend doing a '63 Impala for himself and he asked me yesterday if he should use the NOS quarters he has for it or sell them and get repop quarters since it is a basic no frills 2dr. I told him what I thought they'd be worth so I'm asking here to see if I was close. What would NOS '63 Impala 2dr quarters be worth?
Thanks and Merry Christmas,
Lon
