Johnny,
exactly whats been said.
In a C-10 the main crossmember runs right under the motor mount area and makes it a B%^&h to get to.
You threw me off by saying C-10.
According to your signature you have a K-10,hence more room to work.
Not real easy but alot easier in a K series truck.
ALSO, inspect the rubber mount for ANY mushiness/oil deterioration and if needed Replace it while you have it out.
Thats the more important left side mount,and in foward motion the engine wants to torque up or lift on the left and push down on the right.
And if the motor lifts far enough it grabs the gas pedal linkage with the spark plug stand off at the back of a V-8,pulling it to Full Throttle.
Ask how I know!!
regards,
steve sr.
