Also thank you 250Racer for reminding me about scuffing the steel plates. Just use a fine sand paper to scuff up the surface of your plates.
I've even heard of rubbing the plates on a concrete floor works too.
And here is some Pictures and measurement differences of the install
Here is the spring difference. Both Honda OEM
400EX Steel plate
400EX steel in the middle of the fibers
'89 lifter rod and needle bearing update with the thrust washer in place
Got all the drain plug washers lined up with the pressure plate holes.
Make sure while tightening down the bolts the washers dont get out of alignment, could see it snapping off the clutch basket threads
Because there was a gap with the lifter rod and the pressure plate I was able to adjust the clutch cable.
But if you're out of adjustment slack then you can just add another thrust washer in between the needle bearing and the pressure plate
