Welp, if these are the two brackets that you are refering too then...

The v-bracket is bolted to the front of the block, drivers side, onto two studs. One stud is the mounting stud/bolt that is used to secure your alternator to the accessory bracket. This stud also is where the radiator hose support gets bolted. It goes like this, stud/long bolt thru the accessory bracket, intercooler v-bracket gets installed onto the stud, then the radiator hose support bracket slips onto the same stud, then it all gets secured with a 13mm headed nut.
The bottom side of the intercooler v-bracket is attached to a stud that is used to bolt on the crank sensor. Another 13mm headed nut secures the intercooler v-bracket to the stud. The other intercooler pan bracket attaches to a stud/bolt that is located on the bottom left hand corner of the front cover. Passengers side of motor. Then 3 bolts attach the pan bracket to the side and bottom of the the stock intercooler.
Now, with that said, there are some support brackets that are mounted onto the back of the alternator and the AC compressor that attach to the header to give support. Those are simple bend solid rod painted black support brackets. Installing those can be tricky too, especially if you've never seen them before. The small one, shaped in the form of a J , goes from the back of the alternator to the top stud on the #1 cylinders header stud. The other bracket I believe goes from the back side of the alternator mounting bolt, down to the back side of the AC compressor, then finally to the lower bolt on the #1 cylinders stud. This one looks like two pieces of solid rod welded together. These are probably the ones that you are refering too. They mount on drivers side.
Hope this helps a little.
