What are the correct body bolts that hols the body brackets to the frame. The first parts book [1-2500] indicate a bolt, nut and "cotter", however do not indicate the type of bolt etc. Thanks: Don mddws@me .com or 419 447 5254
That 9/16"shown for the body bracket connecting bolt refers to the head size, not the shaft. I believe that would be 3/8".
The late T's use only a bolt, lock washer and a plain hex nut.
Larry: I just had a 24 Canadian Touring that had never been apart. It had the bolt, nut and a cotter pin on all the body bolts. The nut was NOT slotted for the pin. The pin just kept the nut from falling off. If I get a chance I will look at my USA 1923 Touring that is original. Dan
Sorry: Those were bolts for the body not the brackets. Dan
Seems to me that the shaft on the body to frame bolts are larger then 3/8 as is the head of the bolt on my 1921. If you look at the whole listing for the body to frame bolt/nut you will see it has a 9/16 head and takes a 11/16 nut for a 1/2 inch bolt. At one point they may have been one of those anomalies that come up every so often where the bolt head and nut are two different sizes so you only needed one set of wrenches to work on the car. Many sets of wrenches come; 1/2-9/16 and 11/16-3/4.
