Any tech assistance would be appreciated. currently im changing out the front lower engine mounts on 98' clk. there are two bolts that mount it to the car and to the engine. I am able to access the lower bolt that bolts it to the car very easily, but the to bolt that mounts it to the engine are almost impossible to get to with out removing the exhaust manifolds. What is need to be removed from the engine in order to get to these bolts? Thanks in advance.
