My '64 C10 has Clifford tune-up parts on the inline-six, including intake manifold for Holley carb.
The manifold has a water jacket and 2 threaded holes to plumb into the water system but I can't find any suitable theaded outlet pipes in England.
The threads look too fine to be NPT but they look tapered - anybody got any ideas please?
The Clifford website seems to have disappeared in recent months - does anyone have a contact number please?
Thanks, Simon
