ok finally finished the install today.
for the hole under the battery i didnt really care about the holes being flush so i just made a big hole to suit... although its still touching a tiny bit.
that same pipe also touches my powersteering lines (not A/C). i also had to trim my fan blades aswell as the end of the pipe that connects to the BOV pipe as that was too far forward. the other cut was also the big oval in the original hole.
i was able to onli hack away at my front bar only a little.
i didnt follow the instructions coz i didnt want to cut my reo bar, in the end i mounted it onto the reo at the top and the side tanks seem to rest on it a little, but it is rock solid does not move an mm. i think this is part of my reason why the other pipe hits the P/S pipe. as its too far back.
all in all i could feel the difference today and for the price u pay for this kit it is quite good.
