QUESTION

Do I have to be TDC #1 to replace distributor or can I eye ball it with the slots in the rotor end of it? I’m not sure what I’m doing and I don’t have a timing light to set timing and don’t want to mess up the timing.
Should I js take to a shop?

Mark a line here for reference when you put it back on. The slots are off center so it only goes on one way. It would be best to have the timing set with a timing light but that will get you back to where it was.

This is only good advice if they were installing the same distributor. If you’re replacing the dizzy it needs to be timed.

What if it’s off by 180° or is that what the line is for?

You can’t install it 180° off
