Technical Alu glide question

Theres a square pin under my alu powerglide Im wondering Whats for. And most important, is it solid or hollow. It argues with the hight, as it rests on a crossmember.
Anybody know? Can it be chopped?

 

Is it this part, in the yellow circle? Or something else? Hard to tell from your picture, you took the picture too close to see where everything is.

I think that part is solid, and can be cut off. But it would be good to make sure that is what you are talking about, first

 

Thats the one yes.

 

The orange portion had me . Never would I have guest it was the tail housing.

 

You can remove it. I believe it was part of the fixturing one the assembly line? If I gambled that is where my money would go

 

What you see here is that pin squirrel has shown in yellow. It lays on my crossmember, that can look orange.

 

I was also thinkin that, or a moulding thing.

 

You can cut it off, it is solid cast aluminum.

 

Thanks!
