Quick question about what starter to use.

The 4L60E will have 3 holes on a narrower circle.
4L60E flex has 3 holes and is dished
4L80E flex has 6 holes and is flat. Designed to be used with either the crank adapter or the 99-00 6.0 longer crank flange
To the OP, use the 4L60E flex with your old 4L60E. Remember to take the crank adapter off and use the shorter bolts. If you leave the adapter in place the converter will bottom out too soon and you'll break the trans pump attempting to torque the bellhousing bolts
