There are a few threads here on the subject and videos on YouTube. I had a mishap several months back, bent mine, bent it back good enough to work in an about 10 minutes. Tweaked it closer when I got back to home/shop. It still isn’t perfect but it’s 100% functional and it’s a tractor not a jet, so that’s good with me.
I’d bend it back to functionality, keep running it, and if you want a new SSQA plate when the dealer gets it in, take them the tractor and let them swap it while you wait.
One method:
Another method:
Third method: (Couldn’t find a video. This is the one I used to get it roughed in enough to work while still out in the woods.) Find a fixed object that you can engage with the forward-most side of the SSQA plate while not interfering with the movement of the other side of the SSQA plate. A large tree would work, but if you want to avoid scarring the bark, temporarily nail a 2x6 or something on the tree to protect it. With no bucket, forks, etc. on the loader, put the forward-most side of the SSQA plate flat against the tree/fixed object. Lock the brakes and if you have a ground engaging implement on the three point (such as a boxblade, backhoe outriggers, etc.) put the rear implement on the ground. Curl down (dump) carefully. That should force the side that’s not against the tree/fixed object to move forward while the fixed side stays still, bending the plate back straight. You may have to fiddle with it for a bit to get it close enough for all your implements to fit, particularly if you haven’t straightened similar stuff before.
Like I said before, mine still isn’t “perfect”. It works 100% like it did before with the grapple and forks. The bucket is less forgiving; a much closer tolerance fit. For the bucket, I pick it up slightly off the ground unlatched, roll it ALL the way back against the stops, and then engage the latches. The last little bit it needs is taken up when the hydraulics pull both sides in against the stops.
I bent mine when a limb came through the back of the grapple and lifted the right side latch, unlatching it. I had a rather heavy off center tree/log/mess in it at the time and the grapple came off the right side with all that mess clamped in it. I have since made a tie down for the latches to prevent a repeat. There are a variety of ways to do that. Recommend doing one of them if that sort of accidental unlatching was the origin of your problem. This is what I did.
Edit: BTW, understand the sentiment of stopping payments due to lack of part availability, but that’s more likely to create additional problems for you and no one else.
That and if you have a local welding shop or independent farm equipment/tractor repair shop nearby, they can likely fix it for you in less than a day.
