full conver\'t conversion kit? heres the deal, ive got about 17k in my blazer now and i got kind of bored of it and wanted to build a full convertable 69-72 or73-5 but the problem was i could only find 2 kinds of those blazers, ones that were rusted out or ones that were going to be. they finally pulled their heads out in 1989 and started galvanising the bodies, so i would like to stay w/what i got and make it conver't. is teir any way to do this professionally and maybe use the 73-75 tops? i think ive seen a kit somewhere that came w/caps and some cutting templates or something.
