Just got a big white box from Year One this morning at work. Yeah... just like Christmas morning !
As for the black buttons, they are correct for a `68 Plymouth and haven't been availiable from the aftermarket up to now. As for swapping buttons, mine look like they were chewed on. Is $120 alot of money? Yeah. So was the $295 I paid for wheel well moldings....
Like the old saying goes: in for a dime; in for a dollar.
