My Morgan is from the same period and no issues at all. My headlights were moved back to the original spot and believe if you do it yourself it is only a couple hundred dollars for the bracket. The fishtails look cool but the added weight on the pipes and if these are not stage 1 pipes I would replace them. I upgraded my cams and ecu as well so don’t understand not swapping out the air cleaner and exhaust first. Mine was factory with stage 1 and apparently that is the biggest performance improvement. I loved what the cams did though. Check out garage 56 for new pipes and an air cleaner.
I am a bit of a fiddler on mine so a lot of changes we are making on the later models are more about pride of ownership vs anything else.
The Morgans are great fun and give you something to look forward to. I have a few winter projects planned but keeps me off the streets kind of thing vs anything else.
