I need to talk to anyone who has installed a Specialty Tops Co. Fast Track version on a 73-75 Blazer. I am having trouble with the installation and the reps from the company are having a hard time helping because they can't see what I'm trying to explain to them. Any help from anyone would be much appreciated. The wierd thing is I have installed one of thier tops when it was Kayline and had absolutely no trouble at all. The difference is that the first top was a snap version. Thanks to all members in advance for just reading this. Anxiously awaiting your help!!
