1964 Lemans lower choke tube ???
I have a 64 Lemans 326 2bbl that I'm trying to keep original and found that I have a faulty Choke Tube. On a 1964 the Choke heater tube inserts into the Intake manifold but is inside the exhaust crossover (I think). Any way it is a "U" shaped piece which appears to be welded/brazed to the mounting plate. This piece of tubing has decayed and has a portion missing. I'm able to find replacements for the ????? above the mounting plate but I'm in need of the lower section. Does anyone have the GM part number or can direct me where to purchase this part. If not I may have to try to make one and braze it where it passes through the plate.
Thanks for any help.....
