A dipstick adapter assembly for use with an oil pan includes a front fixture having an inner face, and a backing plate coupled to the front fixture opposite the inner face. A first fastener is applied through the front fixture and fixed to the backing plate with a bond to prevent rotation of the backing plate with respect to the first fastener. A second fastener is applied to the front fixture for application to the backing plate so as to engage the backing plate and move the backing plate toward and away from the front fixture.
