They just re-did all of these on my '67. I do not believe the arms were bent like that on mine. Something must have happened?
Maybe with your engine flopping around in there? A past car accident?
My shop made a special tool to compress the springs. They used a threaded rod with 1/2" plate steel top and bottom. Just like yours, but steel instead of wood. I remember them cussing and messing with these for a better part of a day (2 guys). They thold me that was the worst thing about the entire front re-build.
Thats kind of funny, I used my spring compressors and had them in the car in under 15 minutes per side. I took them out to paint them and cut a half coil off.
