The total gym I have is about 20 years old. The flip chart attaches to two white plastic prongs that come out of the tower. I just ordered the exercise card deck that has two prongs that would go into the tower where the white prongs are. Is there anyway to remove the white prongs from the tower so the exercise card deck will attach? Thank you, Judith White I do not consider myself a p...... customer. I would just like to know if there is any way to be able to attach the card deck to the tower. there is anyway to remove the prongs so I wi[[ be able to the card.
