After drilling rivets out do I have to bend these open like the small tabs? Are the wood corners separate from the top piece?
Yes ,and yes.Have fun.
Don't fully open up the larger tabs that clamp the wood bow to the iron. Only fully open the very small 'clip like tabs' that secure the separate bent wood pieces for the side of the iron.
You will be sliding the new wood pieces (2) into the larger tab, and bend them down and insert to the lower part of the iron. Make the ends of the 2 pieces of lath like wood tapered to go in easy down there.
The new 2 pieces of wood should be checked for length as you don't want the ends to block the full insertion of the long wood bows.
Here is older post on how I did the small wood pieces in the lower part of the iron.
Thanks fellas. One more question. Is the joint where corner and straight top wood a half lap joint or mortis and tennon? Does that joint get glued or just rivets?
Jack, I put an envelope in the mail today for you.
Should have went to garage before asking.
Has this been replaced before or could it be original?
I have never seen a 'Joint" at that location. Model T's do not require glue.
It was just butted together. Corner is two thin pieces with uneven ends.
