1963 Exhuast manifold bolts?

I am looking for a source for a set of exhaust manifold bolts for a 1963. I am not sure where to begin looking any help would be appreciated. Also are you guys putting a bit of lock-tite on yours when installing?

Thanks

Any help would be appreciated! Even if I only get the bolt in I.E. length thread pitch etc....

use anti-seize on the bolts

use anti-seize on the bolts

Do you have one or two good bolts that you can match up? I have had very good luck at my local Ace Hardware matching up bolts and having a good selection of higher grade ones from which to choose. And yes, +1 to anti-seize compounds - just choose carefully since there now are several kinds of compounds offered, depending on application. Maybe it's all marketing BS - not sure. But as an example, I just had my trusted mechanic break both thermostat housing bolts on my water manifold - and that was after soaking the assembly in penetrating oil for 72 hours AND heating them up! So anti-seize is cheap insurance! Still, we managed to rescue the original manifold. Plus he figured that thermostat served the 401 well for more than 30 years - testament to higher quality parts of yesteryear and not the Made in China crap that we have to be careful of today.

If your near high heat use the high temp anti seize.

The bolts should be 3/8ths course thread. Use the manifold as a gauge as to length as they vary in length. The originals had a metal locking tab that is bent against the flat of the head of the bolt. I believe Cars sells these? If not, use a high quality lock washer.

I have never had a problem with exhaust manifold bolts seizing in a nailhead as opposed to the later generation which is noted for broken manifold bolts. But some neverseize cant hurt. The problem I have encountered is that the bolt head shrinks in size from repeated heating and cooling cycles. At that point a metric socket and a hammer come in handy...or as a last resort, vice grips. Good luck,
