Go to Magnumswaps.com and read up on what they've done it's full awesome tech and swap info and a lot of parts you're gonna need. I used the 904 also so you're gonna need the magnum flex plate and a neutral torque converter for it to work together. If you read the website it'll tell you that you gotta drill out one bolt hole a little oblong for all the bolt holes to match up. Also you'll find the harmonic balancer your gonna need for the LA pully to work. As another has stated if your using headers you will have to grind off one of the bosses on the passenger side. Do yourself a favor and test fit them on the stand and do the grinding there. Ask me how I know LOL. Believe me you don't want to do it while it's in the car.
