what is the difference internally between the pre and post 72 904 transmissions ?
Maybe let someone that does it do it if it looks to foreign.
Just tryin to save you some headaches and money.
the important stuff is already done ,just looking for info from those that do know not negative talk from those that don't .
.................Whats the #s on the pan rail on the drivers side........r u putting a shift kit or manual vb........can u post some pics of the differences u found........does the billet drum have a wider bushing in it than ur other 1........if so u need the back half of the new style pump..............kim........
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...
I was thinking that when I read your post and they told me some people do it that way but it requires more math skills than multiply x 10 eh ! lol . Plus I seem to remember I actually traded 1 thick front disc for 2 of the thinner rear disc's to get the good number or maybe it was 3 for 2 I really don't remember either way it was what they recommended as any time you can get an extra disc in it is better than the thicker single disc , they send you 5 or 6 of each in the kit and I think I swapped 1 thick into the rear drum to get the number there otherwise you are swapping lock rings till you find one that is right or machining plates to get the good number .i usually check the clearance with the disc dry.....but there is more then one way to skin a cat...lol
Hey, good job for doing this man. F the naysayers.
............Ya, thats been the style for a number of years in the aftermarket........front seal i use, but u can still get the rear seal from the dealer that has the dust boot on it............kim.........
