Big Block manifold fasteners needed?

[Golden Scamp]

I’m needing to know if I need a set of fasteners to secure my manifolds to my 383. It’s a 68 block and I was recently looking at what the add calls 383 manifold fasteners for A-body specifically. My manifolds are B-Body going into a 68 Dart. Did A-Body BB manifolds need these sleeves[/COLOR] or will I be oK with the basic studs and nuts? The A body manifold may have had a different bolt setup too that requires these but mine are not these ultra rare A Body ones. Thanks for the help.

Answered my own question. If anyone sees this in the future, stock HP big block manifolds require 5 extended threaded sleeves to attach to the exhaust heads studs. The rest use regular studs and nuts. FYI.
