My wife and I recently just purchased our first Model T and it came with a plethora of parts and one thing that it came with that we want to use is a 1926 early (forward stake) bed. The car's bed has already been extended to accommodate the steel bed.
So I have removed the rear fenders and brackets and have the bed centered up and mocked up. Upon just mocking up the '23 rear fenders by hand and no brackets. They will not line up to the holes on the running board and splash shield due to the contour of the fender/the 1-3/4 extension on the bottom of the bed. I have already ordered the '25 mounting bracket setup that was told would help with this problem; however, It seems to me that there is a lower riveted bracket that's the 1-3/4 inch that would make up the difference to get the fenders to line up.
Welcome to the forum! Can you post some pictures of your mockup attempt?

Will do when I get home...the easiest way to try to explain it (without pictures) is that the inner fender that curves in towards the center of the car that bolts to the splash shield makes contact with the bed. Pictures will be up tonight!
