No problem... C-6 is a tranny that came from the 70's era fords. What you want is the foward drum out of one to install in your 4r100. Talk to suncoast if thats were you bought it and tell them you want this because it is fully splined.

They will want to sell you one of there fully splined Billet drums for about $900, you dont need it.
