Sorry. Typo. I meant leaf springs. Your shackle need more angle so when the springs are compressed they can swing. If straight all of that force goes straight into the frame. Like below
Post a picture of your shackle angles. If you have extended shackles the angles may be too straight and contributing to the rough ride. Mine has the pro comp springs and bilsteins. It is very smooth. I believe the sky jacker and procomp are the same springs.
Webers run at like 3 to 5 psi. Make sure you add a fuel pump pressure regulator in line between the pump and the carb. Without it is almost impossible to tune. Go to reblineweber website. They have all the tuning instructions

Part it out. You have some hard to find parts that can make you some money back and go to a cruiser in need. Horn button, switches, hardtop glass, Guage cluster. You name it and someone is looking for those parts.

It looks like 80 series front radius arms used for the front and rear. It's an odd set up to me. I didn't see sway bars either but hard to tell with those pictures. I don't know much about coil over conversions on 40 series but I would think it decreases the value on this one. It may drive...
