You're fine. I believe Carl is referencing SS bolts found at your local hardware store. They generally have a pretty low UTS, about as strong as a Grade 2 bolt. The below link shows what is typically found at hardware stores, 70ksi tensile strength....

ARP, DSE body bolts, etc... are VERY strong. See the link below for McMaster-Carr 12-point stainless cap screws with 170ksi tensile strength.

mcmaster carr sells arp but its higher cost than summit or direct

what i usually do is figure out what size i need then say if its a 5/16" x 18 x 1" bolt I'll look for a differential kit. 12 bolt chevy kit has 12 bolts 5/16" x 18 x 1" with washers. if you buy them separate or a 5 pack they will cost average is $2.40 a bolt plus the washers. it a 12 bolt diff kit you may spend $1.75 per bolt and that comes with the washers.

same with the 3/8" x 16 x 1.25" bolts, i'll buy a chevy intake manifold kit, 12 bolts w/ washers for $2.91 each and the 5 packs are $3.10 each. every little penny helps

Great tip! I've looked into ARP bolts but the cost is crazy. This makes it more reasonable.

This.

But, it also applies to the stainless fastener kits sold by the repro parts houses. From a structural standpoint, most all of it is of unknown quality, specifications, etc. I trust none of it.

Let's not delve into proper length specifications for double shear just yet either. ..... ;-)

One of my biggest pet peeves with suppliers. Not providing proper bolts for their kits. Threads cutting up mounting tabs and being mounted in shear.

Even the OE parts are like this. After using the correct AN standard fastener it's hard to consider going back except on resto-builds.

Do it RIGHT the first time or forever live with a result you're unhappy with. Building these cars needs to be satisfying for many years after you get done - or you'll be re-doing or selling at a huge loss to build another...

In other words - if that's the look you want. Don't skimp and do it half assed because you will be sorry you did.

x3 x4 x5. I did that with my 69 Camaro vert. took a huge bath on it. Now I am in the same boat with my K5, but that is soon about to change.....

I'm going to have to play right field here. It's way to easy to get caught in moment building these cars and get in the mind set of, it's NEVER good enough. The carpet needs to match the drapes, but what I found most important was function and engagement. If I ever built one again I'd focus on what makes a car great, to DRIVE. The way the door shuts, the pedal arrangement, power and heated seats, killer sound system, no squeaks and rattles, great driveability, modern headlights, factory reliability, and the list goes on.. In all honesty, these are many of the things my car lacked. Instead of spending $500 on tail light housings, how about a better pedal set up? Instead of $5,000 on an aluminum block, how about an engaging interior. You catch my drift and I think your ideals are similar.
