My 87 Toy truck has a spark plug that pretty much is welded in there. I tried to remove that plug but couldn't, not even with a 3 foot breaker bar on the ratchet. I almost put my weight on it but didn't,since I did not have the repair kit. Is it an easy thing to do? Here's the plug specs according to O'Reilly's http://www.oreillyauto.com/site/c/search...amp;make=Toyota . This is the kit that I think I need. Is this the kit I need? Thanks
