OK, I'll answer your question with one. How often are you planning on having the thing out??? After 10 years and 55,000 miles mine is still sitting right were I put it when I put the car together. I have flushed the system once and I'm due for another one this spring.

Now for your answer. Mine is in a bracket. the bracket is bolted between the frame rails. The whole assembley would come out through the bottom.
