That is a good question. Unless you are putting the same motor or similar year motor back in is hard to say. I've seen them both way and not always the same from side to side. Also different years have different mounting holes on the blocks. I've even had to use washers to space the brackets to the block. The engine craidle on the truck where the mounts go has changed over the years. Best way to tell ya is just to try different combos until you get the best looking fit.
P.S. The way the bracket are made makes them look bent or off just a little but they are really not, they flex a bit. I've seen them from 0" to 3/4" off but thats the way they came.
