So im on socals website and suncoasts, and i see they both offer their billet flex plates as balanced and not balanced. Considering im on stock engine internal's ill need a balanced one? Am i on the right track? And the non balanced is for engines that are built and balanced internally? So when i get my balanced one am i supposed to line it up a particular way with the crank or harmonic balancer weight? Any in-put on this? I have install procedure from gm service information and thats for stock and doesn't say anything about it. (I cant remember if there are weight on stock set up or not) Also what bolts have the highest success rate, new gm flywheel bolts or arp? Thanks. Also will i need longer torque convertor bolts with the socal flexplate? Thanks

The flexplate will be externally balanced or internally balanced. Your stock truck will require a externally balanced one. So Cals are a little lighter from the ones I have used.
