so it can be full convertable, like the Early Broncos or first gen blazers.
yes you can make anything a convertable if you had the time and money. will it be easy? no. will it be cheap? no. is there a simple way to do this on a bronco? no. will it be cool? depends on who you ask.
so unless you have tons of money to pay someone else to do this, dont do it, OR if you have tons of fabrication skills (which you prob dont because you could figure out a way to do it) dont do it.
if they are done wrong they suck, they leak, and let in tons of wind noise on the road.
