Header installation step five
7. The rear bed rail (square tubing provided by softoppers) installations needs to be flush with the inside of the quarter panel. I drilled the holes myself but my understanding is they will send the rails pre drilled . I cannot provide details on the hole locations because I asked them to ship me u drilled holes. But with my conversations with Bob at Softopper . I would have no reason to suspect any miss alignment and you might save yourself a chunk of work by confirming with Softopper those whole locations based on the hard top your blazer came with .
I think the softopper is a great product and with the Header it really makes the up and down efforts simplified. I gave even run around as a "t" top configuration The part is easily removed with nuts or I had a friend turn down and tap out aluminum shaft and knurled the end and he made a clearance cut to provide clearance of the visor arm coming into contact.( Picture below)
