Default flywheel measuring issue

Maybe some of you math type guys can figure this out for me, doing my measurments they come out to a hair more in the example im posting.

So instead of 0.110 in example im gettin 0.112

So do i need to get a adjustable pivot ball, ive had this in the car for couple years with the 5 speed, seemed like everything worked ok.

Well, got the motor back the other day, used the same flywheel, brand new this time, but there was a scratch in it so i had it resurfaced, bad part its already on the motor.

The example showing the numbers is with the old flywheel, all stock mech linkage and bellhousing. The flywheel is a prw sfi 1645500.

Doing the measurment on the bellhousing as best i could seems im short about 1/16 of a inch.

Hoping i can take one bolt out of the flywheel that is on the motor now and get a measurment........................whats ya guys say, adjustable or go with this.

Thanks Rich

Rich, if you go to the photo and crop a little off the bottom, where nothing relevant is at, it won’t rotate on you. If you then re-post it.

Ok, checked with centerforce today, they said on their flywheels it measures .960, they said they fixed that on pontiac flywheels awhile back, then i checked with prw and they said they flywheels were 9.60, seems the best i get on theirs is .848, so it seems i need a adjustable pivot ball for .112.............shouldnt i be able to make up the difference of this small amount with the adjusting arms.

When checking with summit on the centerforce fw, its says eternal balance, all my stuff was internal balance.

Just dont like the idea of the adjustable pivot ball, worried about that thing falling apart.
