So with my inability to find a gen= 2 RX-7 flexplate I have ordered a lightweight steel Flywheel from RacingBea= t.

My thoughts are to have the 4 bolt holes machined in the flexplate or 6 hol= es in the spline and drill out the rivets to remove the damper plate.

From reading the archives it seems the spline directly mounted is what Trac= y did for the RD-2C but that it's a different spline setup.

Anyone done this? Am I better to continue searching for the auto flexplate?=
