Guys do you need to mess around with TDC and such to replace the dizzy cap and rotor on a NL V8? A mate said I would have to, but from looking at it its keyed so I didnt think there was anyway for me to put it in the wrong way, so it'd just be a case of taking the old one out and putting the new one in.

For just the cap and rotor button, pull the old ones off and put the new ones on. Just be sure to put the leads back into the right holes
