Here are a couple of pics of my early El Camino bracket now residing on my '66.
Those 2 bolts going into the block need to be the right length because if they are a tad long and you go a bit too tight they will punch thru the water jacket on the block. It happens easier than you might think too. Just a little "pop" and coolant runs out of the hole. (I know this with absolute certainty) sooooo, make a feeler guage out of something and check the depth of the holes then find some bolts to fit. Edit: and yes you need a double groove crank pulley. Just get a triple if you plan on adding A/C later on.
