Rear marker lights. Step side same for a dually?

I'm looking for rear dually marker lenses and not finding much. Only thing I'm really finding are early 73-80 step side lenses. Comparing pictures they look the same but does anyone know if they will fit? Would like to replace both red and amber lenses with deluxe trim.
Thanks

Yes, they're the same. That's what I used when I replaced the lenses on my CC dually.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.

I disagree on them being the same. They will fit and work but on the lenses I have seen the pattern differs from dually to stepside.

They are shaped exactly the same. The pattern on the lenses are different. Duallies have the same pattern as the front marker lens on the fenders

Let me rephrase for those doing detailed restorations....

They are not the same marker light but they do fit the location & work as a replacement if your old units are faded, cracked, or missing. I swapped them onto my 89CC dually w/o issue.

The GM part numbers for the dually lenses are 339885-86-87-88
And yes the other ones WILL work

Correct. Each will work but the lenses design are different
