I don't know if there are different length dizzys out there but its worth checking. Is it possible to shove the oil pump down (bend the mount) by forcing the dizzy in when misaligned?
edit: This is a Toyota dizzy right? not a GM DUI thing right?
Yes Bruce, all three distributors that I have are Toyota. One is a vacuum retard points, one is a 60 Seriers big cap and the third is a 78/79 small cap.
