Bolt rear 811 bulkhead to the tail wheel assembly. Torque to specification 70 inch pounds
Rivet to the rear tail skin. (This is where I made a mistake. I was suposed to rivet the 812 rear bulkhead to the skin, prior to the 811 to make the tail wheel slid into place. After considering drilling out the 16 -17 rivets I decided to stay with the assembly as I have it with 811 riveted and then cleco and rivet the 812 bulkhead. This worked well except for the bottom two rivets which required pull rivets. (Learning lesson to slow down and really read the assembly instructions). However it all worked out well.
