Power assist lever arm attachment

A vacuum-mounted clamp for clamping a first component to a second component. The clamp includes a substantially rigid body having an application face, a back face opposite the application face, a side, and a vacuum port extending between the application face and the back face. The application face has a step adjacent the side for engaging the first component. The clamp includes a flexible seal connected to the rigid body adjacent the application face. The seal has a vacuum port in fluid communication with the vacuum port in the primary body and a periphery for contacting the second component to create a vacuum area between the clamp and the second component. The vacuum port of the body and the seal are in fluid communication with a vacuum generator for generating a vacuum in the vacuum area.
