I am SO glad you asked! Back at response #52, you'll see a pic of one side of the crossmember welded in. You may notice several "high water marks" on the body where I had figured the crossmember would sit originally. After a lot of measuring, I lowered that mark to where I actually placed then welded one side of the crossmember to the frame. After sitting the engine in the bay, turns out I was right the first time and second guessed myself into a big fat foulup. Engine sat way to low. So, I very gingerly drilled out the plug welds and removed the crossmember. I've since positioned it higher and with the engine in, I'll be again, welding it back in at (I hope) is the proper height.
One step forward, two steps back.
