Slick 60's

Hi would like to know if anyone would know if the radius rod mount rivet holes are the same as the spring hanger mount holes for a strait axel truck,I think they are just want to make sure.Thanks Bill

My guess is no because isn't the radius arm longer than where the spring hanger goes?

If you have both of them measure where they sit on the frame.

They may be the same shape and spacing but I would say that they're not the same distance to axle center line. The frame is really pretty different from solid axle truck to I beam truck
