They seem like important bolts

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.

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.

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?

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.

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.

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

Back in the miscellaneous bolt bin?

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


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