I hate to be the one to tell ya, but it sounds like you're screwed. When that happene to me, the bolt in the front pulled through the support, and the back part of the seat mount broke. I ended up having to weld the back mount back together and use a large hose clamp to hold the front mount to the support. It is a temporary fix for now. When I get the seats that I want, I'm just going to weld them in. Best of luck on the fix.
