On my 90 Westy, I'm planning tomorrow to replace the exaust collector
(Bentley calls it an Exhaust manifold, P.26.9) along with the 3 gaskets. As
with any exhaust that's lived past its useful life, the nuts and bolts will
have to be cut off. Anyone know what the sizes are of the 7 bolts/nuts that
hold this thing to the associated pipes? Bentley shows them, but I can't
find an indication of what size they are. I've got to pick some up at FLAPS
or my local Napa, stainless steel, I would assume if I can.

In case your wondering, I really think its only the donut seal that's bad,
but that collector isn't looking very good, so I'm just going to replace it
along with the gaskets anyway. Strangley enough, the rest of the pipes (and
cat/muffler) look in good shape.

TIA,
Gregg
