That reminds me of the 'slash and burn' engine pulls I did in my earlier years. When you do a quick and ugly pull you sometimes miss things. Like unbolting the end of the z bar..... You don't have to unbolt it. You can use brute force to pop the engine out. I bet a previous owner did this. Either that or a wreck. One way or the other it's great you figured it out. Not often you can use a hammer instead of $$$ to fix something right! And something just dawned on me, we just proved both of our cars are in 'spec'. Less than an 1/8 inch difference between engine location on our two cars....
