Chandler 48 pretty much covered it but I will add a few more suggestions.
Square the back of the sled to the table saw.
Use a framing square to draw a 90 degree line to the back of the sled.
You can drill the holes one at a time. Drill the first hole in the back then adjust the sled slightly to get the line to add up to the other holes.
Another technique is to put pennies under the miter bar to raise it above the saw's surface, put drops of super glue on the bars, place the sled on top squared against the back of the table and let it set then come back and add screws.
There are a ton of videos on making cool sleds with good techniques. THis is the one I used as the base of my sled.
