I used some of the information in this thread so I'll add my recent spring project to this one in hopes it helps someone down the road. Yes, much can be said on the spring topic but if you are new to suspension work as I was, I think you just jump in and see what you've got when you're done.

I've been second owner on a 69 convertible since 1999. I put rally 2's and new tires on the car about a year after I bought it. Never had it aligned so I shouldn't be surprised that after 18 years the car was scary to drive and the inside of the front tires were down to the wires.

I'm after new tires but felt it wouldn't hurt to do a redo on everything made of 50 year old rubber on the front suspension. On a recommendation from a mechanic friend, I decided to replace everything up front with MOOG brand bushings, upper and lower ball joints, springs as well as steering rod ends. MOOG makes replacement parts for almost everything on the front end. Capped it off with KYB shocks. Purchased parts from RockAuto. My suggestion for this project is to get a spring puller and outsource bushing/ball joint removal and installation on the upper and lower control arms. I also had my control arms powder coated while removed. Once back on the ground with everything loose to prevent binding I felt the front was maybe a little higher than where I started but I didn't measure it.

Prior to new tires I moved to the back end suspension and the leaf springs. After reading much on the net and this forum entry I decided on the Eaton Springs. I called them and discussed the 2 major options for original ride height. I decided on the 126 spring rate 4 leaf (ML3581). I ended up ordering the springs through NPD as they had the hardware kit required as well as free shipping. For some reason ordering direct from Eaton is +20.00 per spring and full shipping on some heavy stuff. I broke at least 8 fasteners getting the rear springs off. I will echo that one should not be alarmed by spinning the fasteners holding the front spring bracket. Stay calm and cut the heads off the bolts. Replacing the clip nuts is simple once the springs are out, you have access to all of it. I blasted off rust from the front and rear spring brackets as well as the rear axle. I used POR-15 to refinish these parts. I was very impressed with the finish. Not a quick process if you follow all the steps. I got everything back together this past weekend and have put a few miles on the car to get some settling in the springs.

To recap the springs:
Front = MOOG 5246
Rear = Eaton ML5381

I'm including some pics as well for you 69 owners for reference. This sits a little higher overall but front to back is pretty much the same as it was.
