Pick out the appropriate one you would need, just need to know whether you need internally or externally balanced, block or bellhousing mounted starter, and steel or aluminum.

The flywheel it has on is 3973457 and the crank is 10114188 but the engine has a vibration i think it may be the wrong flywheel. Do anyone know the gm part no?

Cay,
I dont have the part number here at home, but the flywheel for a 1999 Chevy truck 454 should be the correct one. I do have the correct part number at the shop, but usually do not go online during the day due to a dismal dialup connection. Feel free to call me in the morning and I can give you the correct GM part number. 301-843-5700
