Can anyone tell me the size and length of the body to frame mounting bolts for a 1927 Coupe .... thanks for any help .. Joe
They are 7/16 NF and about 1 1/4 to 1 1/2 inches long.
the front ones are shorter, the nuts on all are 3/4" wrench, heads are different size than nuts, the set in front of the seat are round headed, smaller than carriage bolt head size but rounded, same as the next set back, the rear set in the trunk are longer about 3 1/2 long
A while back someone posted a chart of what size nuts and bolts were used in different locations of a Model T. I'm thinking it was a 'Ford' publication but not for sure. I cant seem to find it doing a forum search. But pretty sure its there somewhere.
From my original, rusty '26 coupe #13,606,xxx:
All are NF 7/16" with hex nuts (fits 11/16 socket)and lock washers. Approx 1/8" of thread shows beyond nut. Measured bolt length each body mount location from front to back of body. Front 1-1/4" Hex head; Near e-brake quadrant 2-1/4" Hex; Under seat 2-1/4" Carriage; Rear frame cross member 3-1/2" Hex head.
Poor Royce, isn't this the third thread that you've posted that diagram in in the past two days?
Thanks for your efforts.
