A damper body extends between an axial first end, an opposing axial second end, a first lateral side, and an opposing second lateral side. A first pair of lugs are disposed at the first axial end and a second pair of lugs are disposed at the second axial end. In the first lug pair, a lug has an axially outermost foot which extends laterally beyond a lateral wall. The second lug pair has a lug with an axial outermost point with a foot extending laterally beyond a lateral wall. The foot on the first axial end and the foot on the second axial end are on opposed lateral sides.

1. A damper for use with a turbine seal comprising: a damper body extending along an axial dimension, the damper body having an axial first end, an opposing axial second end, a first lateral side, and an opposing second lateral side;the damper body having four lugs, including a first pair of lugs disposed at the first axial end and a second pair lugs disposed at the second axial end, wherein:a first lug in each said lug pair is on the first lateral side of the damper and a second lug in each lug pair is on the second lateral side of the damper;in said first lug pair, the first lug extending to an axially outermost point, which is not laterally beyond a lateral side wall of said first lug, the second lug having an axially outermost foot which extends laterally beyond a lateral wall of said second lug; andin said second lug pair, the second lug has an axial outermost point which does not extend laterally beyond a lateral side wall of said second lug, the first lug having an axial outermost point with a foot extending laterally beyond a lateral wall of said first lug, and said foot on said first axial end of said damper being on the first lateral side, and said foot on said second axial end being on the second lateral side. 2. The damper as set forth in claim 1, wherein said damper body can be installed on a seal in either of two orientations, and there will still be a foot facing an intended pocket on a gas turbine engine blade which is to receive said damper. 3. The damper as set forth in claim 1, wherein said damper body also has a pair of radial reaction shoulders on said first lateral side, and a pair of radial reaction shoulders on said second lateral side. 4. A turbine assembly comprising: a plurality of circumferentially spaced turbine blades, each of said turbine blades having an airfoil extending radially outwardly of a platform, with said airfoils defining a leading edge and extending to a trailing edge, with said trailing edge being generally spaced axially from said leading edge, and there being a suction side and a pressure side for each said platform on each of said blades, with a seal and damper assembly positioned circumferentially intermediate a suction side of a first of said blades, and a pressure side of a second of said blades, with said seal being received within shoulders on a body of said damper;the damper including a damper body extending along an axial dimension, the damper body having an axial first end, an opposing axial second end, a first lateral side, and an opposing second lateral side, the damper body having four lugs, including a first pair of lugs disposed at the first axial end and a second pair lugs disposed at the second axial end, wherein:a first lug in each said lug pair is on the first lateral side of the damper and a second lug in each lug pair is on the second lateral side of the damper;in said first lug pair, the first lug extending to an axially outermost point, which is not laterally beyond a lateral side wall of said first lug, the second lug having an axially outermost foot which extends laterally beyond a lateral wall of said second lug; andin said second lug pair, the second lug has an axial outermost point which does not extend laterally beyond a lateral side wall of said second lug, the first lug having an axial outermost point with a foot extending laterally beyond a lateral wall of said first lug, and said foot on said first axial end of said damper being on the first lateral side, and said foot on said second axial end being on the second lateral side. 5. The turbine assembly as set forth in claim 4, wherein said damper body can be installed on a seal in either of two orientations, and there will still be a foot received in a pocket on one of said first and second blades. 6. The turbine assembly as set forth in claim 5, wherein said damper body also has a pair of radial reaction shoulders on said first lateral side, and a pair of radial reaction shoulders on said second lateral side. 7. The turbine assembly as set forth in claim 6, wherein both of said first and second blades having a pocket adjacent the leading edge, and a post spaced toward said trailing edge from said leading edge on both of said suction and pressure sides, and one of said first and second feet being received in said pocket of one of said first and second blades, with the other of said first and second feet being on an opposed axial side of one of said posts relative to said one of said feet. 8. The turbine assembly as set forth in claim 7, wherein one of said radial reaction shoulders on each of said first and second lateral sides being positioned radially outwardly of one of said posts on each of said first and second blades, and the other of said radial reaction shoulders on each of said first and second lateral sides being spaced axially from said post.
