ON the drivers side bottom bolt I went up from the bottom with an 18" extension then used a universal adaptor on the end then used a 2" extension and then the socket.
The top one I used a ratchet end wrench from the top of the engine. I had a worse time with the top one than the bottom one.
If you drop the down pipe the passenger side is real easy.
The other thing I did was pretighten everything on the bench and then install them so I did not have to mash the donuts as much with all the extensions stuck together.
