I'm looking for info on lifting a 620 as well. Can't figure out how to build a spring over set up with the lower spring plate having the shocks hooked to them. Now I'm looking for extended shackles. Any suggestions? thanks.
Good morning all - 1st post. I'll search but still thought I'd ask.
I am trying to lift a '78 620 a couple of inches and am having trouble finding info on the rear shackles and springs. Is there an extended shackle available that will fit the 620 and lift springs - if any exist.
Thanks for the help.
