Need help with speaker wire connection to ARC Classic 60

A) Bend the fins down enough to fit a spade.
B) Bend/trim the spade enough to fit between the fins.
C) Both

I wouldn’t bend trim or modify your Classic 60 or you’ll just hurt it’s value. If you don’t have the skills, no disrespect, have Chris at VH Audio or someone else make you some jumpers so you can use other heavier cables. Cardas, Audio Quest and others make spades that work just fine on your amp. The dividers/fins are plastic I recall so they’re not going to bend easily and again it’s a classic amp and I wouldn’t mess it up.

I have no desire to modify the amp.  I ordered some Kimber Kable 8tc in bi-wire configuration with bananas on the speaker end and bare wire on the amp end so I can terminate once I found the right solution. 
One thought I had was to bend the wire in a hook and solder, but I’m not sure how good of an electrical connection that would provide.
