Most of the changes on the '69 are body/interior.
The engine is stock with the exception of Webers - USA versions came with SPICA
The car is mostly a street legal track car - fiberglass flares for wider tires, fiberglass trunk lid/hood for lighter weight, the interior is bare - just 2 race seats and a rollbar, aluminum dash.
It allows it to run at the local "vintage" races - would not be legal for anything too fancy - but for fun locally, it is good.
It's a nicely set old car - made to resemble a GTam car.
The previous owner did most of the conversion after the car was sideswept on the road by a bus. I just made some small changes for ease of use/driving and enjoy it as a pretty but cheap track car. No one will ever mistake it for a real valuable Alfa - and it will never be invited for a real fancy vintage meet - but that's not what it is supposed to be. - the bodywork on it however was done by someone that knew what he was doing - the flares are very nicely integrated - better than most flares on old GTVs I see
The Jr. is pretty much stock - which is very nice as it has a real vintage feel
