Header question

Yep they are ancient I bought them over on the cudachallenger forum from this great guy named Tony he was a super good guy. He basically gave them to me and I paid the shipping on them that was back in 2003 probably
The only hint/help I can give from here is to raise the car up as high as possible, then figure out a way to raise it another foot.

Or put the driver side in before the engine.
