I do not think your going to find a set of headers that do not require you to remove something to install them. My Youngest had a 68 with a Small Block and I remember removing the Starter to make it easier to get that side on and I also remember disconnecting the the shift linkage to get the other side on. Both sides were installed from under the car. I did have to buy a bracket to mount the Alternator, but other than the exhaust nothing was permanent.Does anyone make a simple drop in set of headers for this car? It's PS, PB, A/C, Auto on column. I mean no permanent modifications, not removing plugs or disconnecting shift linkage temporarily.
