    1.th400 of course
    2.this flex plate-http://www.lmperformance.com/4050/1.html
    3.trans cooler
    4.5/16 steel line to run up to trans cooler
    5.perferablly aftermarket shifter
    6.custom length drive shaft which Spohn makes for this application
    7.a tune from a stock manual car to be flashed in since this trans isnt electronically controlled
    8.you may also need a th400 cross member which spohn also makes

    optional trans temp gauge...

    i just had another thread where i did this same swap except it was a th350....next time try to do some searching first
