1963-66 top question

My FSM tells me to lower the top 1/2 way and push OUT the vinyl between the bows so the top folds flatter and doesn't pinch the vinyl. , before I was doing that it sat about 2-3 inches higher and the boot was a monster to get on. After doing it the FSM way I could lower the top into the well and get the boot on easily.
Done that too sometimes but never really paid attention to the lowered height, will do so the next time I go for a ride. Thank you!
