Reply To: Here is another photo of the windshield locks that do not fit.

I have the same twist locks on the windshield of my ’33 model 836.  The part on the windshield looks the same but the part on the top of the dash is lower so the latch can pass by.  The part on the top of the dash is flat and is inset into the dash so it is almost flat with the top of the dash. Looks like what you have are raised so the latch can’t pass by.  Hope this helps.  Don
