I think most people have this same question,I as well.The way I did mine is the way countless others have done also. It's a must to have all the parts for this installation on hand including the shifter and console.Make sure your transmission gear select arm lever is all the way forward that puts the transmission in park.connect all the linkages together
1.) Start at the bottom and work your way up I used a 2 "hole saw to cut the whole in the floor just don't cut the dimples out there should be 3
2.) Mount the torque rod plate to the floor pan with 3 screws in the 3 dimples. Drop it through the top and connect all the linkage under the bottom and to the transmission,this helps you to line things up and also allows you to correctly position the shifter
3.)Then get the first bracket lined up on the side of the hump and secure it ,I tack welded (they line up rather easy I was surprised) mount the top swivel arm(I guess thats what it's called)into the first bracket you tacked in and install the top shift rod linkage,remember your tack doesn't have to be solid it's ok if you can move it a little it actually helps so you can get things lined up as you go.
4.)Take your next big bracket ,this is where your shifter is a must, place the bracket on the side hump and place the shifter into the bracket and screw the shifter into place in the bracket, connect the shift rod into the shifter assembly side,everything is going to be loose and make sure the shifter is in the forward position (park)If you have connected your linkage up correctly and made sure your torque rod is parallel then this will show you exactly where to tack weld your main bracket .
5.)The last bracket is to secure your console,if you don't have your console I recommend waiting to do this step. I placed the console on the mounted brackets and screwed the console onto the main shifter bracket to locate it in the correct position,after securing ,open the console door and mark the two screw locations on the floor,remove the console and line up your last bracket you'll probably have to do this a few times to get it right . Here is a pick of mine completed.I can take some new photos tomorrow and do some measuring if you'd like.I hope this helps you out some.
