I'm back and I need help; mashed frame

[whodat90]

Greetings all! I've been winging forever, but low key. I just picked up another '75, and started working on it. I'll link to my flickr rather than giving the whole story in this post (that'll be a separate post when I'm done) but the short version is that the one I have has been in an accident. NBD, lots have been down. The problem is that this one was rear-ended at an angle, and it bent the horns that stick off the back of the frame and hold the shocks and seat. I have a spare frame I could cut up for parts, but it's a very low serial number and I'd rather not. Anyone have a derelict GL1K frame they'd be willing to sell, or cut in half and sell me the back half of? Thanks!
