Before reinstalling the right Gear mount, I decided that I wanted to fix the problem with the AN470-4 rivets that were in the seat bulkhead and causing a puckering of the front floor pan, I drilled out the 5 offending rivets and fashioned a chip chaser out of a 6" ruler and was able to clear off the rivet heads after they had been drilled, I was worried this would creat a bigger problem that I had initially, but the idea of leaving it as is wouldn't set. It turned out just fine, and with the rivets removed I was able to go back in with the LP 4-3's and finish it off like it should have been, Took a little over an hour to fix, and worth the effort. The Landing gear went back in without any problems, re torqued the bolts/nuts, and reinstalled the brake lines running from the tunnel to the gear mounts.
