It don't matter if your just dropping pan to change rear main seal. I've done it and if I can do it you sure can. You have to take off the cross over, the fly wheel /TC shield. The smaller bolts up front are a pain to reach. Fairly labor intensive but alot cheaper to do yourself then pay a mechanic to replace rear main seal. Actually on GNTTYPE they have a section that tells you exactly how to do it. Look under Rear Main seal replacement. I didn't even think about clearence issue I just did what the instructions told me to do, if it looks like tight clearence just bump the ignition a little, it'll go in at the same angle it came out. Hope this helps.
