The original unit in the truck has the flange (with the hash marks) at right angles to the vacuum chamber, whereas the new unit had it inline with / coming straight out of the chamber. My mechanic and I couldn't get the new unit to sit properly, w/out it hitting the engine.
ChevyDuty says their unit is for 1947-1962 ... so whats wrong with this picture? Do I have to somehow modify the vacuum advance unit...or is there another style with the angled flange...and if so...where does one find it
Your help would be most appreciated.
thks,
Bart | | |
