Can anyone who has done this testify to them working??? I am wondering if anyone has both coils and RCA blocks and if it solved your issue. Thanks guys!!
so a friend of mine just made a plate that raises the engine by placing it in between the motor mount that raises the axle back into position. says he has very minimal to no vibrations.

now, is this the same as getting RCA blocks placed on your wheels raising or keeping the axle alignment with the trans?
so far he doesn't have any complaints.
