I'm sure this has been asked many times here, and I did search, but I can’t find the answers I’m looking for. I have a ’75 with an all stock suspension, bushings and such have been replaced. I want to lower the car just a little, nothing too crazy or unsafe. Right now it site about 29.5” inches at the center of the fender wheel opening, I would like to get this down to around 26” – 27”.
I understand that a 550 front spring set will lower the front of the car a bit. Also I understand that longer spring bolts in the rear will allow me to lower the rear.
Here are my questions:
Will the 550 springs lower the car 2” – 3”, or will I have to cut them?
Do I need an 8” or a 10” bolt to get 2” – 3” lower in the rear?
Finally, how difficult will this be to do in my garage with standard hand tools? I have jack stands, a jack, and hand tools, but changing the front springs sounds dangerous.

Thanks in advance.
You will have to cut the front springs.
Go with the 10" bolts and you can cut off what you don't need after the ride height is correct.
The front springs are not complicated, but you need to take care or they will bite!!! You can do all of this with hand tools.
I've removed rear coil springs in the past using a spring compressor and jack. On my 75 there does not seem to be a way to install a compressor. Is there a safe way to do this without one? Also, what is the easiest way? Unbolting the spindle and lowering the control arm with a jack?

You don't need a spring compressor on these because of the deep upper spring pocket. Just put the car on stands and a jack under the control arm with only a little bit of tension(about an inch or so of control arm travel from full droop). I also suggest using a good floor jack, NOT a bottle jack, bottle jacks can tip because of the possible angled load. Set the jack so the wheels allow the jack to move inboard with the control arm movement, its a small but still. Also make sure you have enough jack travel to lower it enough when done, usually just a few inches past droop. Remove upper ball joint nut and use ball joint seperator to break loose. Be gentle during all of this and make sure the jack is VERY secure. Also hold on to the spindle so it doesnt flop when it frees. Slowly lower jack. Keep the lower ball joint attached during this. You dont need to romove it for just a spring swap.
Good luck with it!!

I have an 80 and if I remember correctly I think my stock fender height was 29".
I installed the 550 springs and I have 27-3/4" center fender height and I have a mono spring in the back and had to get 10" bolts to get the 27-3/4" center fender height. So it dropped about 1-1/4" with the 550 springs.
I want to do the same as you; I would like to get a center fender height of 27". I am going to start with cutting a half coil at a time to get to 27".
only cut a half coil at a time...ask me how I know. and I disconnected the lower ball joint not the top. I guess you could do either one, but the lower was no problem. try hitting the very front of the lower a-arm with a sledgehammer (look for the flat pad) iinstead of the using the pickle fork, you might damage the ball joint boot........again as me how I know.
Well I placed my order. I ordered a 550# front spring set and a pair of 8" bolts. I was a little off in my current ride height dimensions. It sits at 28" in the front and 29" in the rear. I want to bring it down to 27" all the way around.

If you don't mind. Can you give me more detail as to how you made the swap?

Removing the upper is much safer, its not under tension when you have a jack under the lower arm. And yeah only use a pickle fork if your replacing the ball joint, I use a tie rod seperator or other type of puller (depends on what I'm working on). If the ball joint is too stuck for that then you should replace it any way so out comes the fork. When using a seperator protect the thread ends with a nut. Thanks for bringing it up, I should have mentioned this in my earlier post.
