guys who use aftermarket suspension parts

[old Rusty C10]

My wife has been really supportive of my many projects including several squarebodies and shes been wanting a second creation for herself. For years shes wanted to do a 50s era truck, but finding something in decent shape for a reasonable price has been a real effort.
A couple of weeks ago i found her a body, a 1953 International 110 Pickup. It looks alot like a chevy of the era, and she thought the truck was cute and all so i bought it. The truck looks like it will fit well on a shortbed C10 chassis as there is only a 1 inch difference in the wheelbase between the two

Heres the squarebody questions

Has anyone used a tubular control arm/ coil over set up that does not lower the truck, and do you have a part number manufacturer and source for said set up?

Also has anyone found a good four link set up with coil overs for the rear that is somewhat easy to install? again part number, manufacturer, and source is appreciated

If you guys want to be super nice id love to see pictures too.. Thanks in advance
