64 Dart GT conv. value?

I paid $2400 for my 64 Valiant convertible last Xmas. Good paint and most all trim there, decent interior, no top, spoke wheels, slant engine. I don't know what "V-8 chassis" means. I think the only missing part to change to V-8 is a dropped steering link and motor mounts. It would cost a lot of money & time to round up the missing trim and parts, so I agree w/ $1500 tops.
