Because the tranny bolts are really hard to get to. The top bolts. Do you go over the top of the tranny from the back to get those? I did that once with a 6 foot extension, but could not see the bolt, just blindly trying and finally grab the bolt with a swivel socket. The heater hoses are in the way. Just remove those, but I guess I'm wondering if I will need to tilt the engine. I have solid motor mounts, so that is an issue if I need to tilt it. I have to do this all myself. My Z buddies have all moved away. ;(. Thanks very much for your response. Good time to put in my AshSpec radiator I guess too. Any advice to look out for guys? Think I should replace my flywheel bolts after reusing them 5 times now. Clutch bolts too? Thanks all
