Exhaust choke heat tube

[Loren L.]

I need the outer diameter measurement for the exhaust choke heat tube that passes through a 2 1/2" 3797902 exhaust manifold. I have two of these and Bubba must have found a better use for the tube.

My car is a 65 350 HP with the 2.5" exh (not sure of the s/n). I measured the chromed, near-verticle tube coming up off the exhaust valve that feeds the carb's choke tube and it is 0.251" OD.
