Help me Identify where these bolts go!

[Rodosuta]

They seem like important bolts

[Nissanman]

The pair in the RH pic. look like conrod bolts.

The ones with the knurled ends may be to hold the tach and speedo in the dash.

[C.Costine]

2X connrod bolts. My roadster has only around 25 bolts still in it and I haven't seen any like the ones on the left.

[bobd]

Neither one looks like anything I have seen on my roadster. The bolts look like they could go through a bushing and I can't imagine what the knurled screws would do - possibly carb linkage?

[mshort07]

Don’t think it’s carb linkage. They’re over 5 inches long and about 1/2” diameter.

Are the bolts in the bottom picture the bolts that hold the front of the rear leaf springs on the frame?

The 1st picture bolts - haven’t seen them before.

[theunz]

Do you have an after market air filter/ filters? The knurled ones are obviously made for something that only needs to be finger tight. If they go to your car, then they are for something aftermarket. I did a frame off on mine and did not have anything like those on my 69, don't know about any other years.

[Toptech360]

The bottom picture bolts look like leaf spring front hangar bolts to me. Not sure on the knurled top pic bolts.

[GeoffM]

Back in the miscellaneous bolt bin?

[JT68]

The bottom picture bolts look like leaf spring front hangar bolts to me.

I think this is correct if they are the right length.


Don't recognized the knurled ones either- what size thread are they?
