Help Identify These

I've been going through the parts I got from Pat in St.Louis. I've found a few that I don't know what they are. Their supposed to be early chevy parts probably 2nd Gen. If you know what they are let me know.

Pic 1 no. 1 is fuel sender flange, no. 2 is ???, no.3 is throttle linkage.
Pic 2 no. 1 is door bracket and pin for fold out step, no. 2 is an engine lifting point.
Pic 3 I think is window hardware (don't hold me to that).
No idea what is in pic 4.

Later,
Rip

Rip the large shinny nut on the item in pic 4 has been added as a spacer. It rotates freely.

I "Think" #2 in 1st pic are brake parts(for adjusters) I know I have seen part in pic #3."??? Last pic looks like a muffler ,or tailpipe hanger???

Thanks guys! After Vanish and Rip said fuel sending unit flange then I realized what the large O-ring was that I had to dig out of the trash.

Tom I've got some brake parts out in one of my parts trucks. I'll compare them with the ones in the first pic to see if they are adjuster parts.

I'll look inside one of my doors to see if the stuff in pic 3 are window parts.

Where are you Don???? Did I come up with some things that you don't have

For some reson I Think the parts in pic #3 are for a 2nd gen belly pan(plastic) side splash shields??

Thanks Don! I'll check the rod tomorrow. I've got the side door on the 66 apart now so I can see the lock rod in it easily.

Rip was right about the clip for the side step in pic 2. I found the bolt holes where it attaches.

I think that pic 4 might be something that someone other than GM put together .

Tom do you know what years they used the plastic side shields? Both of my second gens have metal ones. Most everything I got from Pat came from a 67 sport van.

I had a 68 Sportvan that had them, as does my 68 G-20 from CA. Don might be right, and there from the heater??? To hold the core in on a 2nd gen???

OK I'll check the extra heaters that I have.

The small rod that's threaded on one end isn't a door lock rod, it's to small.
