I just got a frame in the mail and it has these DT shifter boss covers on it...

What are they, why would they be there?

How should i remove them with out damaging the frame?

Those are the inner stop plates. You should be able to slowly work them off with a flat screwdriver by lightly prying from the back - use a shop cloth to protect the paint. Strange looking plates, tho - what is the frame and what was originally mounted on it (parts-wise)?

It doesn't appear that they've been brazed to the frame bosses, so you should be okay.

As DD suggests, put a shop rag across the tube to protect the paint. If you can't simply pry them off, you should be able to tap them off gently from the back side using a hammer/rubber mallet and the end of a flat screwdriver.

Maybe hit them with a bit of penetrant and let sit for about a half and hour? That might aid in the removal.

also, you're in Illinois. Set frame outside for a couple of hours to get really cold. Bring it in and hit those things with a heat gun or hairdryer, then tap. May pop right off.

I wouldn't pry them off. I'd use a wide-opening pliers to reach across from side to side, perpendicular to the plates. Grasp each edge and slowly rock them off. Less chance of damage to the frame.

You can use those backing plates and a 10-sp set of Campagnolo bar end shifters, and have 10-sp downtube Campagnolo shifters.

I'd be interested in pics of the whole thing. I have a ~75 Colnago Super F/F that's my current project.

I think a Park cone wrench would slip under those plates. Then tap tap with the small end of a Warrington hammer. Or anything with weight to it.

How does that work? Those DT stop plates lack the small tab that actually stops the shifters forward motion. I'm confused.

I would pry anything off, especially using the tube as the axis for a lever, protected or not. Something will move, the part of the sidewall of the tube!

I'd get a small gear puller, some penetrating oil and ease them off

That thing is called the frame. You don't need it, 'cuz they are pretty common items. After you get those valuable ears off it you can send me the frame. You can keep the ears.
