'95 APV plugs

I have read and heard a number of posts about rocking the engine forward. I have tried this and there must be another mount besides the top dogbone on an APV. My engine doesn't rock forward after removing the dogbone and shifting to neutral as I have heard stated. I have 2x4s, ratchet straps and assorted prybars and no luck. I also have SERIOUSLY rusted and corroded plugs and have been spraying PB blaster (front 3) everytime I am under the hood in hopes I can get things to loosen. It seem to be so rusted I cant get a plug socket far enough to get around a plug, let alone loosen one.

I have a tool that you put in place of one of the dog-bones which allows you to ratchet the engine forward for access to the rear plugs. It cost me less than $25 at Harbor Freight and you'd have to pry it from my dead fingers to get it away from me, it's invaluable.
