before I converted over to electronic, I had a problem with tach cables and the 90 degree drive unit. I tried one tach cable from mail-order, then had a local shop make one that was the exact length as the original. Both were either noisy or the needle jumped.
I removed the 90... rotated the dist and could then attach the tach cable directly to the dist without the 90 degree adapter. Had to re-index the plug wires on the dist cap.
Though the chrome dist shield needed modding a little bit (vacuum advance transducer was now hitting the shield on the rearward side - so I notched it).

Mine worked fine untioll that day
and while i still have all the shielding, I put in an HEI unit from D.U.I so the sheildinhg is on teh shelf now awaiting poilishing. Im probably just gonna fix mine, as i have no desire to convert to electroninc yet......but you may end up with the solution ill use if this should happen again
