This is the first time I've seen one of the speedometer faces bubble like that. The speedometers we offer are remanufactured units which means cores are sent in "mainly 85 MPH because they are so readily available" disassembled, and then rebuilt with the same internals that the 140 speedos use. Latemodel Restoration Supply stands behind our products and will make sure that any warranty issues are taken care of. Please give us a call toll free at 1-866-507-3786 and speak with one of our sales representatives to get a replacement part for you.
