1 bolt through the bottom of the trailing arm & 2 possible choices for the top of the bag: a) 2 bolts through the bottom frame rail + a larger hole for the air fitting; or b) fabricate a 'hat' that bolts to the bag & weld a single stud in the center of the hat to use the original upper bolt hole.

Choice 'B' is easier because you can fab the bracket on a table & it bolts right in. The alternative is drilling that larger hole for the air fitting (easy enough if you can flip the frame; a mf-r if you get to lie on your back to do the job).
