I installed all brackets correctly on my 1998 Chevrolet K1500 but had serious problems. 1) The transmission mount is over 1/4" higher than factory. This was stressing my transfer case causing it to leak. 2) Using these engine mounts caused the transmission to "click" when the accelerator pedal was released .I think this is because the halves have to be separated to fit, which allows the rubber to move under tension.These mounts are not easy to fit and most likely caused the above problems.I removed them and a different brand The rubber material itself looks top notch but no attention was paid to the actual dimensions and installation process, I really wanted to like them.
