Duster 340 oil pan

If you look at the picture of the small block oil pan in the MP catalog,you'll notice that it comes with a "dimple " and so do the oil pans in my two 340 small block cars But as you say ,it' s probably for steering components clearance.
I thought so too, fst340rt. I will take a closer look at the pitman arm and center link, but I surely don't want to reinstall the engine just to find out that I have to remove the engine again to replace the oil pan. I just want to be sure it's going to fit before I reinstall the engine. Don't want to have to do it more than once!
