700R4 3/4 clutch stack?

I am working on a 700 from an 89 GTA Trans Am. I removed the 3/4 pack and it has 7 steels and 6 clutches. The rebuild kit has 6 steels and 6 clutches. This is what I am used to seeing. Was there a stock configuration like this or was this something a previous builder may have done to cut down the clearance. I know I usually shoot for .060-.090". Seems like this would have been really tight.

I set up all of my 700s 3/4 clutch pack clearances at .040-.045 I have also seen as many as 9 and as few as 6 clutches Old school thinking was to add as many clutches as you could but the steels became too thin to properly dis ipate heat. Most new technology states to use kolene treated steels and a good quality friction and keep your clearances to the minimum side of the specs
