904 differences

you can put 5 alto read and kolene steels in the 4 disc drum....you need the .061 thickness disc..and .068 thickness kolene steels..you need at least .060 clearance in the front drum...

i usually set my at .070....i take the pressure plate to a machine shop and he surfaces/grinds it .010 to get the extra clearance...

I have done 4 904s like that....3 are being used...one in reserve...

The billet drum I`m useing has a relocated groove for the lock ring to accomplish this very thing , the Guy`s at TCS were very helpful when I did the clutch packs , they recommend .010 per clutch disc with no more than an extra .010 on the total ,this after soaking the discs for at least an hour , I left mine soaking over night and the Wet stack worked out .005 over the .010 x The # of discs which they told me over the phone was perfect .

PS sorry for the vagueness on some things I actually did this rebuild last fall after getting back from my journey I just haven't gotten to swapping the trannys yet . I'm trying to get all my ducks in a row before I do , the new lines should be here soon and I'm going to do the swap then , can't wait to feel the push of the tighter converter and this trans was already a go-er when it was behind the stock 318 I never should have gotten talked into trading it for the 727 that's in the car now .
