since the column shift has been changed to a console i'd keep it that way.
imo changing to a console shift doesnt hurt the value if thats important to you; i think more people would prefer it.
you might want to look for the 70 chrysler padded console top pieces but they will taken some hunting.
what colour was the interior originally ? i'd guess saddle tan because of the dash pad and top boot
heres a pic of the saddle tan coloured console tops in my 70 300
