Is it just me or does this spring compressor not work on a stock 69 Camaro lower control arm? The hinge block with the arms up is a little too big to feed through the lower shock opening, feed it in the long way with one arm up and the other down and I couldn't get both arms up due to internal spring diameter (Hotchkis BB springs).

Local Autozone and O'Reilly's only have this model.
Is this the correct style?
Thanks
