Ok, You can do the EZ mode on the firewall, it worked for Me it will for You. when You have all this space cleared behind the engine and You are ready to start installing parts use a car scissor jack between the tranny and the firewall (You can cut the fw lip before this too) and maybe You can adapt something to it so You can use a ratchet and socket to turn the jack and You do it until You get enough space to clear the pipes and some extra space. You Do want to cut the lip a little bit so it will be easier on the tranny/engine mounts but I've done it and saved Me time.
