72 Scamp Rear Leave Spring bracket removal help / suggestions?

Thanks for the feedback,...I did flood the backside of the bolts, for two days. When loosening them, they came out without heat.
I used a 6 point deep well impact socket , on a 1/2 drive ratchet with extensions bars. It Worked perfect and gave me the leverage I needed. :)
I used a whole can of PB Blaster rust buster and soaked them well. I had to have a catch pan under the bracket for the amount of penetrant I was using,
but well worth it. Thanks to Motorpirate and to AJ/FormS for the plan B method.
