with a little help from my friends we got a set of dog legs off a 57 superior. I had the man cut them off at the door opening and a hand width passed center line of the rear Axel. they did good and I got plenty. I knew they would be longer them this eureka as superior put there molding on the quarter. so now the question comes up were did superior get the length? the front end is the same. as is the chassis. the quarter on the Eureka is 77 and 5/8 from the edge of the rear door to the edge of the body at the taillight. from just under the molding on the front door to the same spot is 170 and 3/8. any one (Rocky) with a 58 superior that could measure it to see if the bodies are the same length or close? here are the measurements and what it looks like after 3 hr. of work.
