I'll put in my
This all depends on how needy the car is. Lets say it doesn't have to be torn completely down. The body can stay on the frame. What I also do, is start be removing the engine, transmission and rear axle(lets say it has one because if it's in need of restoration, hopefully its on old car with rwd) and everything in the engine conpartment.
Then I rebuild the entire suspention system. Rebuild my engine, transmissions, rear end. Paint it all nice colors
Undercoat the car, or paint it, depending on your likes. Get rid of all body rust, paint engine compartment. Put in engine, transmission, rear end. Then I restore the interior. I rip out the dash, door panels, seats, carpeting. Restore them all to orginal condition. Then the final thing to do is paint the car. After all this, expect about...3 years to have passed and a lot of things in between going on. Like problems and things you've missed
It takes along time to do such work, but I personally can't get enough of it. Anyway, hope this helps.
