I just ordered a rebuild kit from them for my A904 and I ordered it directly from their website. I called to speak with someone in sales before I clicked the go button and he was very knowledgeable with what I needed. My question had to do with the amount of friction and steels I would need. He said the kits are packed with the maximum necessary for the application. I.E. if the maximum number would be 4 friction and my trans only takes 3, the kit comes with 4 and I don't use 1 of them.
