We tried inserting it that way, but when ever it came to fitting the big spikes through it was a no go.

We’re going to try it 6 ways to Sunday again……on Wednesday. Lol.

Thank you. Eric

Do you order it by application or size? I'd say you need a smaller one.
EDIT: After looking again that probable is the correct size.
