I bought the Hooker 2055's for my '86 Z28 and am in the process of the install. I got all the old crap off and put the drivers side on. I got 3 spacers with the headers for the longer bolts that the accessory brackets go to. The instructions say to user the stock studs, but the non-threaded part of the bolt/stud won't fit thru. It's slightly too big. Has anyone else had this problem ?? Thanks for any info ....
