Since I am needing to do all suspension bolts front and rear, my retirement budget was going to be stretched thin to go to one source. I needed to find best prices for these bolts. Our main vendor source will get a big order for an asundry of items related to this maintenance, but unique to the Vair.

I found all the Grade 8 yellow zinc bolts and Grade 8 yellow zinc nuts at Bolt Depot. EXCEPT the 12-20 nuts. Those I found only at Clark's, Grainger and Tacoma Screw, Grainger was cheapest and had to buy pack of 25, but I am thinking there was a typo in web ad and would be like Tacoma's price. Tacoma Screw you needed to buy a pack of 25. I only need 10, so it is simpler to buy pack and give the rest away. Rick is doing same task on his Corsa's front suspension, so we are sharing the 1/2-20 nut purchase.

Thanks for the very useful information. Makes it easy to have all the hardware required ready to go before you start the job. Makes it so much easier to "disassemble" when you don't worry about saving the fasteners. Now that we know what it should be "break out the smoke wrench" if it gives you any lip. Lol!
I do not know how much price difference there is between vendors but for small orders of fasteners or bearings or formed rubber or seals I normally just go to McMaster-Carr. They are a bit more expensive than Grainger but carry a much better selection and always has them in stock. Normally an online order will be at your door within 2 days. For small orders of hardware,bearings/seals, etc, getting the order "complete" and quickly on the first attempt has a value. If you don't already know about McMaster-Carr take a minute and look around their website
McMaster.com If you know what you need you can find it there.

Hex nuts, Zinc plated grade 8 steel yellow, 5/16"-24, 2 pcs
Hex nuts, Zinc plated grade 8 steel yellow, 3/8"-24, 4 pcs

A couple more nut sizes that be helpful.

You will need 11/16-18 nuts for the front strut rods. 4 pcs

You will need 3/8-16 nuts for rear stabilizer rod. 4 pcs

I will post the dimensions for the 8 bolts that hold the torque arm bracket on the body and the bolt on the onboard end of the rear control strut.

On the original front strut rods, I cut the nuts off and have a 11/16-18 Die to run down the threads. And like to use new wide nuts and the performance type bushings.

Check out AMK. While they don't have Corvair kits, they have an extensive selection of automotive hardware for Chevy and other brands. They were the only source for the screws that go through the inner door shell to the wing windows on my '65 El Camino.

Prices are very reasonable with the only caveat being their minimum order is $30.

Grainger had the 1/2-20 grade 8 yellow zinc nuts. They also had black oxide. But you have to buy a package of 25. Reasonable cost, also.
