SBC Exhaust Manifold Bolts
I have a 1981 Chevy 305.
I am installing a set of Rams Horns on it.
However, all the mounting bolts were lost.
I was told that these bolts are 3/8 x 16.
8 of these bolts are one length and 4 of them are longer.
Does anyone know what length each of these bolts are?
Also, 1 of the bolts/studs that holds on the exhaust pipe is missing.
What is the size of this bolt?
And there are 4 small plugs with square heads on each manifold--
What are these plugs called?
I was told that these plugs are 1/4" NPT---is this correct?
If anyone has any of these bolts, I would like to buy them.
