Hi all! I have 5 bolts that measure 5/16" dia.x 1 and 11/32" long from the shoulder to the end. I think these bolts belong to the engine but not sure? any help .the engine was disassembled when i got the car. most all bolt and nuts are easy to identify except these. thanks Ken
Differential? If so you are missing two and the nuts.
Thanks Jack for your input!I rebuilt the rear end about three months ago and bought all new bolts and nuts for it and i don`t recall any bolt of this size.also these bolts don`t have any holes for safety wire. Ken
I am wondering if they the blind bolts that go into the hogshead near the starter, or the front timing cover bolts that require no nuts?
The hogshead is not installed yet! I`ll check that out. Thanks. Ken
Andy,all those bolts are 3/8 NF thread.
Maybe they are for the oil pan to the block, the later ones that used a lock washer and nut with no cotter pin? I have some just like it and they are about the same size as the ones with the cotter pin hole I think. Jim Derocher, AuGres, Michigan
Agree with Jack, that size is correct for the rear pumpkin (axle case) bolts, Part # 2503E.
If they are 5/16,that is the only place I can think of .
My first thought was timing cover bolts.
Hope this helps.
Where did you find that diagram? Sure would like to have a print of it in my shop.
Other than the 7 bolts and plain nuts around the diff centre, the only other place I can recall 5/16" bolts being used is the four which hold the handbrake cross shaft to the chassis, and these are drilled for split pins and have castle nuts.
Hope this helps.

Doug that's a great diagram. Can you email it to me in full resolution. I would like to get it printed at a local printer and frame it. Garage art! John
Thats a great bolt diagram.
I wonder why a neat restoration tool like that isnt avaliable from the suppliers?
It would make real sense to have one for the restorer!
I have to ask the question, is it a Ford product?
I thought I had seen most of the ones by Ford over the years.
Whoever its from its a very useful diagram.
wow..great diagram. What do the number next tot he bolt/nut size mean? For example: Take the upper left most as an example - the rear spring hanger nut. What is to the left of the 11/16th in that illustration. The first looks like an open ended wrench.
When looking closely at the diagram I just noticed that the number of wrench to use is next to the size bolt.
That must be a shop print to use at a Ford dealership. Maybe?
Question: are the wrench numbers the same used by Ford for their tools?
Maybe some of you tool guys can answer this one.
Try a standard nut on them. They look like the later open style pinion bearing bolts on the end of the driveshaft. If the standard nut doesnt fit, chances are they are a Ford thread which should narrow it down. troop
Thanks for all the help and suggestions guys! These bolts were in a unmarked bag when i bought the car.since i am fairly new to the model t, i do a lot of homework. they will probably find there place somewhere. thanks again all, Ken
Mystery solved! I compare these bolts to my diff. housing bolts and they are the same. guess the other owner had some extras.now i do! Ken
John, I am on vacation, but when I get back to the office, I will try and send it to you then. Happy New Year from Daytona Beach!
I had so many requests, I retrieved the file and sent it. Hope you got it.
