Evening folks. Will soon be getting my engine back from the rebuilder and will be getting ready to place the engine and tranny back on the frame. Question comes into being on the 327/300hp with a powerglide, the AIM shows a hardline vacumm going from the modulator on the tranny to the back of the AFB (I have the 3310S), I have been unable to find this particular piece of vacuun hardline and would like to see if anyone has any suggestions on the size of the line if I have to form it myself. Also The AIM shows an elbow that the vacuum hardline goes into on the carb any suggestions for that piece would also be appreciated. I will still be using the left rear stud to feed the vacuum for the Dist. and the washer system, ect. Thanks for any input and assistance.
