Did degree mine but would think it would not be necessary with that lift, matched springs & otherwise stock components. Obviously ragtop has a geometry/component issue. Hopefully degreeing in this instance would solve problem or help identify issue. Hopefully badsport is on to something and it is something easily corrected for you ragtop. If you go the degree route it is a PITA especially the first time but take your time & here is one great info. video among several on the web plus the great members here are always available. Keep us posted.
