Hardware needed

[Captain Obvious]

Speaking of hardware needed, Anyone know what hardware was used to attach the starter on the mid 70 cars? Here's a pic of what was holding the starter in, and I'm not sure either of them are correct. One has a "7" on the head, and the other has no marking. And there was no captive washers on either bolt.

Here's what I took out:

They look like the same bolts used on my 71.

Thanks @bluez, but I got a follow up question... The two bolts that came off were different. Which one was like yours? The one with the 7 on the head?

And did your car use any captive washers, or was everything loose?

The carparts site is back up.  It has some stuff.  Looks like the parts taken out were half right.

Just looked both bolts had #7 flat and lock washers as well

Thanks guys. So the parts manual says the two bolts should be different lengths. One of them is 35mm long and the other is 45mm long. And that makes sense... I just took a look at the starter and the two mounting ears are different thicknesses. The upper one is significantly thinner than the lower. 

I have the 35mm long bolt here, but I'm missing the 45mm long bolt.

Anybody have old hardware lying around? BOLT-HEX M10X1.SX45  (M10 bolt, 45mm long, no captive washers and has a "7" on the head.)

I recently bought the bolts from my Nissan dealer if you have a guy there that will work with you.

Thanks guys. Those bolts on ebay are "close" and are "fit and function" correct, but not quite "form" correct though.

I'm finding that much of the older hardware from the early cars is non-captive washers. Makes sense that as the car sales took off and production increased, Datsun quickly switched to easier to assemble hardware (with captive washers), but that's not the case for the early cars.

I could certainly use newer style hardware. but I'd really like to have a bolt like what was originally used. No captive washers and no indent on the head. A little dirty, with patina, and unrestored would be a bonus.

Odd, my M10 "7" bolts are all 1.25 thread, and my 1.5 thread bolts are all "9" bolts

I'll look at some more, but so far it is the same on a big handful of bolts.

@Terrapin Z I will double check the size and pitch of the bolts the next chance I get. Thanks, and I'll let you know!

Bruce, I think I have one. I had to replace mine yesterday because my new starter has a thicker flange.
