I'm fixing an exhaust leak and I'd like to replace the rusty manifold hardware while I'm at it. I'd like to maintain the stock heatshield but it doesn't have to be concours correct. At the same time, I'm not interested in a fancy 12-point ARP set.
Does anyone know of a kit, or what lengths the bolts should be? I believe there are two studs on the passenger side for the pre-heat tube.
Truck is in the shop, so I can't check it out myself.
Thanks!

Re: Exhaust manifold hardware for a '68 w/390 ?
So, I'll answer my own question know that I have the information:
The original hardware seems to be:
qty 14x) bolts 3/8-16 x 1.25"
qty 2x) hex collar studs 1.25" x 3/8-16 x .6" -- for mounting the air intake pre-heat shield The original hardware was ramp-lok bolts which have a special anti-slip design with integral washer.
Interestingly, the Ramp-lok bolts--and many other original style bolts for our trucks and other classics--are available from:
AMK Products
Bolts:
Kit# F-537

Studs:
B-12474 - correct style but needs to be cut to length.

Re: Exhaust manifold hardware for a '68 w/390 ?
Thanks for posting that! I have an exhaust leak, as well, on my 71 Truck w/360. I was wondering where to get the right kind of bolts. Great find on that web site - I've bookmarked it, and will plan on getting my new bolts from them.
For the gasket, I bought the Fel Pro gasket w/heat shield.
This is the next big thing I have to do on this truck - it will be a challenge, but I think it's going to work out great. Good luck to you, too.

Hopefully your's isn't as involved as mine was. On my truck, both the mating surfaces on the manifold and heads had some deep rust pitting. On top of that, all the surfaces had a C-shaped arc to them. Ended up having the heads pulled, machined and refurbished. On the bright side, I have hardened exhaust seats now, new guides, seals, one new valve, etc. so the heads should be in good shape.
Sure is nice to have the leak fixed finally.
