Changing spark plugs and seat belts

I am pretty mechanically inclined but slammed on the brakes when I went to see how hard it would be to change plugs on my '97 T100. Is it rocket science? :confused: Looks like maybe individual coils are blocking access. Any help would be apprecieated...... thanks. And how about the sticking seat belt returns? Panel removal looks like a pain to get access for removal. Toyota dealer wants about $160 labor for each belt r and r.:disappoin

Plugs are not as bad as they look...took me about 1 hour the first time. just need a really long extension for your rachet as the plugs are recessed in the heads. The coil packs just pull right off and the boot is attached to the coil pack. There is another thread on here about changing the plugs. Nothing to it really. Just don't over-tighten and use anti-seize on the threads. You probably also need the dual electrode plugs.

Thank you, sir. Chiltons manual doesn't have a real clear pic on how to deal with the coils. Figured once I got them out of the way I'd be fine. This is my first rig with individual coils.
Thanks, again.
