    I think that is aluminum plate stock for making your butt rib closeouts from the butt rib ends to the front and rear spar carry-thru tubes. A very difficult little project.

    Any more info on the butt rib end plate would be helpful. looks like they are only needed on the front butt rib? Is there a template or more of what they are suppose to look like. also how to attach to the rib.
    Thanks,
    Ted

    The butt rib closeout cuffs are probably the most fussy and challenging part of the whole project and it is an area where you get almost no help from the build manual. The following thread gives some good information on how some of us did it:

    It seems a lot of guys (including the factory I think) are not bothering to install any cuffs on the fore and aft end of the butt ribs. Their only purpose is cosmetic and to keep out cold drafts. A good tight fit around the carry-thru tubes is only necessary if you want to try to seal out all drafts from this area. Even if you do, there are plenty of other places drafts will come in. Some guys just stuff foam into these areas in the winter.

    On mine I fabricated them from 0.012" aluminum sheet and used Hysol to attach the pieces together and to the butt ribs. You have to make your own cardboard templates and fuss with them until they fit to your satisfaction.

    To complete a total closeout of the butt ribs you will also have to make some sort of a clear window to go over the fuel sightgauge cutout.

    Thanks Jim,
    I'll give it a try, the foam also sounds good. That link is very
    helpful. I also have that option above the doors.

    The 'close outs' do nothing to add functionality or style. The windshield cover s everything. IMHO, a waste of time and materials.

    I agree with Floog. "Waste of time and materials ".
