Rear Seat reinstall help for Grandpa's 62 Valiant...

Wow, that looks nice. I don't know, I am always appalled by how violent you have to be to get the rear bottom cushion out or get it back in. Maybe it was easy for some UAW guy in Hamtramck back in the day, but after 60-odd years of work-hardening it seems really difficult to compress the steel spring frame. I am afraid to hit it that hard because if I miss the hidden frame I could punch through the vinyl. Basically, you have to slam it back and down, bruising the heck out of your palms if you are like me.
Thanks...Will persevere!
