I/o port seat brace NEW
 

Looking to get 90 ish. It cost me ~100 and restocking fee is 20% + i'd have to ship it to return it. I'd rather just sell it and not loose more then 30 bucks. It doesn't come close to fitting with my boss frog bar/harness bar. Never even took the protective coating off the pieces, it just arrived today.

Hmm...

What diameter is your harness bar?
What diameter does it look like it was intended for?
Does your price include shipping?

It would include shipping
I'll measure my bar when I get home from work, the problem isn't diameter it's clearance for me.
