At one point, I had reproduction door panels and the repro emblems with the longer studs. IMO, the emblem quality was fair at best (they actually looked OK until you compared them to a set of originals) and it was almost impossible to start the push-on retainers on the emblem studs. I actually ended up threading the studs. Even doing so, I had to heat up the door panels and press the emblems into the panels. It never ended up looking right. Then, when I found out how poor the fit was of the door panels, I tossed everything and went back to a set of nice original door panels and original emblems.
