It's in! kinda. ended up at the range for a while Saturday, then a car cruise with Hank, and excuses #3.
so after quite a bit of moving and thinking and rearranging and thinking and staring at it, i found where it'll live for good. i was actually able to get the transmission back onto the factory mount in the factory location! i could get the engine about 1" higher if i drop the trans mount by an inch, but meh. the last picture is actually hood clearance before i moved it down an inch to get the bell housing off the tunnel. this way any XJ kit or parts bolt in no question.
so the trans mount is in/done, and i have the engine mount kit with the block and frame side plates done, just need to fit and weld in the rest. fuel lines are right there and i need to get it started and make sure i don't have to screw with anything while it's back out for mount welding/paint.
