That's the first pics you have posted?
you sorted it, good work Kurt.
For any given period the 175, 200, 250 and 277 Blizzard frames are the same. The only difference being brackets, gussets etc for varying applications of either road, Gs, scrambles, military etc.
Yours is a road Bike frame, probably why it is still straight, looks OK from a distance. Which of course makes it a good starting point.
If it were mine, I would gusset and brace it in several areas if it is to survive the trauma of scrambles or motocross.
Areas where they commonly fail under duress. I will get some pics up in a couple of weeks of where I know they fail.
Keep an eye out at your local scrap dealer for a trashed shipping container, and see if he will cut you a couple of the GOOD square feet out of it for gusseting and bracing stock.
