Changed mine a couple months ago.
I had to loosen up the rear mount and then take off the bolts that attach the starter to the rear mount. I forget if they were bolts or nuts but its easier to take them out then mount the starter and rear bracket together. Too many things in the way. The rear bracket is required or the starter will eventually twist on the front two bolts. Make sure you re-install it.
Don’t forget your spacers between the starter and the engine block.
Disconnect the battery before you start.
I put the back up on ramps then jacked up the front on jack stands for addtional clearance.
That was the toughest part.
