just like the heading says, locking t-tops with a key. these t-tops are off of an 88 Firebird but will fit and Firebird,Trans Am Camaro etc from 1982-1992. I will not ship these t-tops b/c they are glass and could to easily shatter. I am going to mpls on the wkend of April 16th so I could bring them up with me then if someone there would be intrested in them. $125.00 for the pair, firm.
