thanks for the wheel data, as for the bolt mine on the car, the carriage bolt have a turned up end, on one side of the head.
Another problem is, one of the front 21 inch rim is not from this car, it has the lugs welded on like used on the ford model T. but today I showed the rim too a guy who spent the last 30 years with ford model T, and he was sure it was not a ford rim.
the lugs interfere with the seating of the rim with the wood spoke section of the wheel.
yes cutting off the lugs you might think would solve the problem, but to add to the problem, there is a 1/8 inch raised edge just past the lugs?
so now the diameter is smaller, again bad fit, this is how we bought the car and got it home.
So my point is i need a 21 inch rim that i can put a new tire on.
