who knows the correct size of the bolts that attach the body to the frame in a early model t? are there washers used?
Great resource Steve!
Front mount bolts are hex bolts 7/16"-20 x 25/32"; center are the same size but 1" long, and the rear are also the same size but 1-9/16" long. All have drilled shanks and use a castle nut.
I think there is an error on the list that Steve linked to, but what a wonderful reference.....
On the radiator mounting studs I have seen, all have been drilled at both ends, one for the split pin for the nut and the other end for the pin on the retaining plate.
3929 1909 - 1916 Radiator Mounting Stud 3/8" 2 7/16" 24 None Drilled one end, threaded both ends 2
3929B 1917 - 1925 Radiator Mounting Stud 3/8" 2 7/8" 24 None Drilled one end, threaded both ends 2
3929B-2 1926 - 1927 Radiator Mounting Stud 3/8" 3 1/2" 24 None Drilled one end, threaded both ends 2
3929C Radiator Stud Nut 3/8" 24 Castle 2
I found a couple of errors too. I contacted the webmaster about them and he corrected them. Today I noticed a couple of others, so I'll tell him about those too.
Steve, if possible, please let us know when all the corrections are incorporated so that we can go and pull the corrected chart, thanks!
