Dodge cam eccentrics vs GM spacers.
 

I am putting GM C30 spindles under my 1973 D200 project in order to use a GM lower A-arm to eliminate Dodges strut rod. To increase front end ground clearance,
and make the front end Z easier. Then on another plus side it opens up Wilwood aluminum calipers too.

Luckily both the Dodge, and GM control arms are with in a 1/8 of each other.


I can use a GM upper control arm by welding the mounting point to the frame.

Or I can modify the Dodge upper control arm through strategic application of a cutting torch, drill, and a grinder. To install a GM upper ball joint.

So now for the question.

Which system of alignment is better? GM's spacers or Dodges cam eccentrics?
