No sir, I'm running the stock aluminum pan that came on my l32... I did have to notch the bottom motor mount bracket about a 1/2 inch wide and 1/4 inch deep in two spots. But that was no big deal and even doing several test fits to remove as little material as possible it only took 10 minutes.
Then on my 98 the water temp sensor was different, everything else was the same besides the TB of course.
