I am new at the suspension stuff so please ask me for info if I leave something out. I don't know what I dont know yet. I have a 1954 buick century, Just purchased and the motor and transmission were removed in preperation for a chevy 350 swap from the nailhead motor and whatever transmission so the drivetrain is gone but it still has the torque tube rear end.

I want to do a triangulated 4 bar set up with coilovers in the rear. and probably a fatman stub kit up front. I will probably follow through with the chevy engine set up as I have one just laying around until I can afford a better set up. I wont be drag racing or street course racing with it but I want a good solid performing street car. It will be some time before I can afford to do it all so I figure I have time to ask some questions and educate myself. so here goes.

1. I want to drop the car 2 inches from stock height. With a stock set up everyone says just get new shocks and springs. With the 4 bar set up how do I calculate the ride height for a 2 inch drop?
should I just set it up for stock height and then get lowered coilovers or is there more to it with a custom set up?

2. When I install the 4 bar for 2 inches lower will I have to notch or modify my frame or modify my interior?

3. Can I install all of this without removing the body? all the videos I see have the body off for obvious reasonsbut im not sure if I can do it if I dont have to modify my frame.

4. there are many makers of these kits out there. Is there anything I should be looking for that would be specific to my application in the buick?

5???? Anything else I have missed on the large scale? I know there will be more when I get into the install and set up that I will need to educate myself on but what else do I need to know or ask when looking for a kit.

Thank you for your help.
