Hi Paul and Alan
I just got done looking at both of your pictures and comparing them with my car and everything's identical to yours. My can and vacuum tube is right up against the bracket. Now I have a different problem that the position of your # 1 plug wire isn't the same on mine. The wire in that position on mine goes to the right bank ( probably # 2) instead. Yours goes to the left bank.
Time to get the books out.

I'd leave well enough alone.

The 1969 AIM, UPC 6, Page B6, shows a diagram of the correct position of the distributor. The vacuum nipple of the can points ~105° clockwise from straight ahead. That puts it more rearward than your photos show yours are. The AIM agrees with the diagram in post 12. Positioning the distributor correctly as the diagram shows gives the tach cable a straight shot to the drive fitting. No need for those 90° gimmicks, or kinks in the tach drive cable.

I have dug out My AIM (also Page B6) for the 1972 Corvette and it agrees with your analysis that the Vacuum nipple is set at (as you said) at 105 deg. from the forward position of the car, which coincides with Post #12 above. That's with the #1 plug wire on the right side of the observation window and the rest of the wires installed in firing order going around clockwise.
That said, mine is really messed up to what the AIM shows and thus why the Vacuum nipple is hitting the shield bracket. Looks like I need to pull the distributor up and move it a couple of notches (Clockwise I think) to be able to get the vacuum nipple at the 105 deg. position. that serving a two fold purpose , giving plenty of room for adjusting the timing in both directions and to allow the tack drive cable to install in a straight line.
I should be able to turn the engine over until I achieve TDC on the timing mark on the crankshaft and then pull the distributor up and rotate the rotor clockwise a couple of teeth and seat it back down and rotate the whole distributor clockwise until the dist. cap visually aligns with #1 wire tower and re-time in the new position.
Sound a bout right
Sound about right I hope.
