 Which dimensions? hole spacing? Diameter? Hole size? How exact do you
 need... I happen to have one off the plane right now :-)

 Dave you are insured. Sky Smith had the info on you. You are famous.
 As far as I can tell you can fly the RV4 anytime.
 Apparently two successful off airports counts for a lot :)
 I need a medical and and bi annual. Both have recently expired. I got them for
 flying in Oz.

 Jean, I received the damper plate today. All is well. Thanks.
 If someone hasn't already given them to you, I picked up my RX-7 flex plate from
 the hangar today. I will measure it tomorrow if you still need them.

C. Smith Thank's for your response of received the damper plate,yes i still need the holes dimensions on the RX-7 flywheel just to compare if both are interchangeable, but i found an idea to use the RX-8 flywheel and the standard Tracy damper but Paul recommend 4130 instead of aluminum plate but it will add a few pounds, you see the rx8 one  is design differently then the rx7 with those big holes away of center holes and closed to the ring gear and by using a bolted plate to the original holes 12mm the Tracy damper plate by attaching the rubber bushing holes and are line up with the rx8 big holes for the bolts head clearance.There is a sketch for this additional plate no welding and no balancing i guess it worth to try.
