So, I keep mentioning this "Shelby Drop." Time to actually show what it is. To sum it up:

- Three factors make lowering the UCA an improvement in handling. First, this modification to the suspension lowers the center of gravity on the front of the car; second, body roll is reduced by 7% to 9%; and third, the camber curve is improved.

So this is what the template looks like. If you notice, the holes are not "centered." This is on purpose. The 65/66 cars have the A arms set at an angle, if you make the holes straight down, it will move the mounting point forward or backward. But with the new holes offset (AND ALWAYS TOWARDS THE REAR OF THE CAR) the A arm will be lowered vertically.
You also want to use bolts that are very tight, otherwise you won't get the holes right. I originally tried to reinstall the A arm, but there isn't enough room to drill.
I also had to go buy a new cheap drill. I've needed a 1/2 drive drill about 50 times and never had one, and it sucks trying to find/buy large specialty bits for a 3/8 drill. This job requires a 17/32 drill bit if you want to do it correctly. I ordered my template and drill bit from the link above.
Also don't forget to put something on the backside of the holes so you don't slam into your manifolds with the drill bit.
