Flexplate Tolerance???

I'll try and make this as easy to understand as I can.
I notice during my test run (engine on a stand) that my flexplate did not seem to be perfectly flat. So, I removed it and laid it on a glass table to check flatness (straightness). I can slide a dollar bill under two opposite sides of the plate. So, should it be perfectly flat? How much tolerance in flatness is ok? I can afford to buy another one but if I can slide a bill under it also, do I keep on until I find one perfectly flat?

Thanks
Willy

I have seen flex plates with a lot more than a dollar bill out being flat for sure ..

Your torque converter will stiffen it up anyway

If you had any doubt about it I would replace it. Its worth the cost of buying a new one to reduce the chance of ever having to pull that engine to replace it. Ive been there done that.
