I am having trouble getting the rear bolt off the passenger side of my 1990 L03 exhaust manifold.

There doesn't seem enough room to get a ratchet, or wrench up there as it is tucked behind the stock exhaust flange and the ratchet hits the side of the body...no room when looking from the bottom. Is there a special tool to use???? or just push it up and down so the break is made and the bolt is exposed to get a ratchet up there. There has to ba an easier way....

Please advise anyone else...sure there is who ran into this mess.....

BTW....driver side is a piece of cake!
