Frame tweaked and rear shackles?

[ascuro]

Just got my 6 inch lift finished up yesterday, and after getting an alignment, the tech said my frame looked pretty tweaked. Said I'd probably have to get it straightened out by a shop - if anyone's ever had that done, about how much am I looking at? What about the frame strength/integrity after straightening? I'll have to call around tomorrow for some quotes I guess.

Also, more importantly - has anyone found a source for stock/replacement rear shackles for a 70 blazer? I can't seem to find anyone who makes them, and they're not exactly abundant in the junkyards here. I'm also not quite ready to go for a shackle flip just yet (plenty of other more pressing things to fix first). I was thinking maybe some short front shackles might work? I was gonna call the dealership tomorrow, but guessing that's going to be a dead end...
