Listers,

=20

I have a question about the four bolts that secure the intake manifold =
to
the exhaust manifolds on our 6-cylinders.

Over the 60 years the threads between the aluminium (note correct =
spelling)
and the cast iron have been sacrificed, rendering the bolts unreliable.

The parts manual tells us they are: HBZ 056  -  3 =BC=94 x 5/16=94 with =
the end
thread 1=94 long.

=20

Though an unusual bolt, I think I can source them here in NZ.

=20

My question is:  What is the thread?   UNF or BSF

=20

TIA
