Unclemeat,
Very sorry to see this and hope you are not injured.
Assuming the frame and engine are original, my advice would be to bite the bullet and have the frame straightened by the best house you can find. In my case, and from complete ignorance back in '03 when I started my rebuild, I decided the $300 to straighten the frame was too much. I thought I could buy a frame much cheaper on eBay, which I did. Back then, I didn't know the resale value (as if I would sell this motorcycle) that matching numbers adds. Also, I didn't know that later A10s had a cross-shaft through the swing-arm spindle for right-hand brakes versus the left-hand rod pull on my '55. This ended up with me needing to change the swing-arm spindle and bushes (the latter being a task I gladly would have paid $300 to avoid - a very long story). Then, I did not have a boss in the frame for the pedal pivot of my rod-pull brake system, so I had to add this myself at the cost of buying a wire-welder (not completely sunk money, as I like having it). The story goes on. I am sure you wouldn't have the kind of problems I did (being a plunger, for example, and probably more awake), but it seems that having a frame that is good except for being bent is better than buying one that may have a bunch of other problems, which may also include being bent.
