I purchased a replacement lock and found the Cylinder is to large. Catalog say one size fits all. Upon more research I have found there actually was a larger one made and found on some cars. A replacement is not made. Anyone run into this and what solution was found.
Not sure but check out 28-29 model A pickup door lock
Not necessarily pickup try various 28 29 model A cylinder locks
That replacement door lock fits up to 1948 Ford pickup trucks, and works on a 1926-27 with about 3/4th inch cut off the square shaft to make it the right length.
I sent an email of a possible contact for locks.
