In many cases, you have to spread the frame a bit and sawzall that bolt out and deal with the rest of it on your bench. Regardless of who owned it before, anyone who goes through this treats there new parts like gold
Just take it apart every year, lube it up and your chicken!!
All our government does is distract us while they steal from us, misspend our tax $ and ruin our country
