Trouble getting a slant six in the car

Wow. I have never had to take off a bumper to pull an engine. A, B,Or E body. Damn.
I got it in the mount but now the problem is I can’t get the driveline back in. I mean I can’t possibly be expected to try and rip the engine in and also try and guide the shaft in. I’d have to be in two places at once. How is it done??
