I finally got around to removing the inspection cover on my transmission last night (owned the truck just over a year) and was pleased to see a LUK clutch in there. How does the clutch material thickness look in this pic? I googled my brains out but could not find data on how thick a new one is.

 

It's hard to tell when you dont know the construction of the clutch and how much material you can loose before you hit the rivets.

 

I must have been tired when I posted this morning - each of the clutch friction material plates are right around 1/8" thick - does that help?
