Need help with valve covers!

[red98bird]

Doing a head swap for a 98' perimeter bolt and I bought these valve covers for center bolt heads off ebay. The oil fill tube won't fit because there are two metal protrusions on the new valve cover, but the perimeter bolt valve cover only has one. I ordered a oil fill tube from an 02' and that doesn't fit either. The valve covers came off a GM crate engine.
Any tips are appreciated.

Grind one off???
Don't know I use a breather with no filler cap

Thanks, that is what we ended up doing, the only problem is that we can not screw the oil tube all the way in until it locks because it will face the front of the engine instead of being straight up. What I will end up doing is ordering passenger side from GM and changing it out later.

Do you have any pics of this? My filler tube is crooked and it really looks bad, even though nobody notices it, it bugs the crap outta me!
