Did the same as you on my 1970 SDV and powder coated the control arms and etc., so undercarriage of car looks new with more durable finishes. Picture attached before re-installing. There are no replacements made for stops, so had to re-use existing. Cleaned them up real good and put them back, using screw driver to force the "fishhook" style sections thru metal slots. The only way I know is re-use and a screw driver is the install tool. Car drives super nice and tight.
Your right the front springs were difficult.
To get all the rattles out the three front body to frame bushings, one under battery, one under radiator, and one under overflow should be replaced too, they are not too bad to replace.
Replaced rear suspension too, same deal only rear springs are easy if you use spring compressors.
