i have been working on y 67 with a 326,and factory air.

i want to replace my valve cover gaskets,i did the drivers side with no problems.
but i can not seem to figure out an easy way to get the bottom rear bolt out of the passenger side under the A/C box.

it seems impossible to do,so does anyone have any tips,or ways that they have removed it.

thanks for any help.

I've got a 1/4" drive ratchet and a short extension that fits.
