i put the engine and box in at the same time.. ca box not stumpy..
i got the box over the steering link.. lifted it up the rear at the bellhousing then i dropped the cross member out and lined up the engine mounts etc.. then i just jacked the crossmember back up again...
i had 3 jacks and an engine crane all helpin to manouver it in.. oh yeh, i have a pit in my garage so that kinda helps :P
i would recoment denting the firewall back a little bit around the bell housing and a gentle massage the whole tunnel to help a little bit.. although i didnt.. took about 3 hours of fukin round to get it in without smashing the booster..
