You're right, it's much easier to simply remove the cross-member to get more room at the plug. Plus it'll give you a chance to add LOTS of anti-seize compound to the threads on those cross-member bolts...they like to rust pretty badly.

Next week I'm buying two 1990 Celicas...one with a shot body and the other with a seized crank bearing. $600 for both, two days' labour to swap-in the good engine, and I have a nice car to fart around in. Oh, there'll be hell to pay...
