AMD 73+ Duster fenders

I ordered a pair on Dec 26 (Boxing Day sale in Canada) and got the call too about taking the seconds. I asked about a further discount to take the seconds (which turns out to be an incorrectly positioned lip on the fender mounting surface, up instead of down) but they would not do an additional discount, so I said I could wait.

My only concern is that I've paid for them already.

Me to in October paid for them.
They said 60-80 days for the right ones as of yesterday.
Summit, just last night gave me 10% off if I would accept them.
They said minor grinding required to make them fit.
So the minor grinding removes 50% of the strength of the top lip, they told me just a minor tab........These might just be shipped back.
