3/4 inch electric impact for 75% of the cot through floor bolts with no wrench on bottom. 24% needed wrench on bottom, and 1% needed cutoff wheel because they were above rear axle/torsion bars, exhaust pipe, and air bags.
There were 30 seat belts attached to L brackets & chair rail, so..... 30 nuts & bolts for the ratcheting belt end, 30 nuts & bolts through the floor, and 30 bolts & nuts to the chair rail.
Gonna have a sale on grade 5 nuts & bolts! I've got about 30lbs
