Where as earlier ecotec engines that had a auto trans don't have the dowel pin holes drilled. So if you want to put a manual box behind one of these auto cranks you will need to have it drilled for the dowels or run the flywheel without the dowels.
Some have had no problems doing this where as other have had bolts come loose or snap. Your choice.

The dowel pins were added to the manual crankshaft later by GMH when it was found vibration would work the bolt heads loose on the flywheels of the Ecotec engine. Dual mass flywheel & clutch weigh about 20 kgs. The flex plate & torque convertor might weigh as much in a auto set up, but the torque convertor also acts as a big vibration dampner. So probably will never see the same harshness & vibrations that a manual does.im a bit confused as the auto flexplate has no dowel pins it just 8 bolts, im just wondering why the manual needs the 2 dowel pins put in, if the bolts on the manual could come loose, couldn't the auto flexplate bolts do the same ? there would be just as much weight with the torque converter on it as a flywheel with pressure and clutch plate on ?
Does the exedy solid flywheel conversion kit have only 8 bolt holes in it , or does it have the extra 2 holes for dowel pins
the pictures posted by you OZ38 do you know what model engines they are from
According to this info: http://forums.justcommodores.com.au/v6-development-modification/18486-ecotec-auto-manual.html
and other information I have found, the auto and manual ecotecs ARE differently balanced. Therefore even if you use an ecotec flywheel, you STILL need to get it mirror balanced. I have been driving around with a misbalanced engine for 7 months! This information needs to be in the original post!
