$25 to have mine done and it's being done with my shortblock rebuild right now. $65 is a ripoff, Not like the flywheel is 3 feet in diameter. Its just a little bigger then a brake disk, Ask them if they charge $65 for disk brake grinding, lol or tell them to get it done in 15 minutes you'll do it. Not your fault they are so slow it takes an hour to do it.
