Hello everyone, I am looking for some assistance in determining the mounting point locations for the rear upper control arms from a C5. I am installing the suspension and drive line from a C5 into my 67 Camaro. I have just completed the front frame section and am about to start on the rear. I have been using the picture shown below to determine all of the mounting points for the suspension cradles and upper control arms. This was easy for the front because it gave me everything that I need.

Unfortunately this diagram provides limited info for the rear upper control arms. It looks to me that datum "M" is defining the forward surface of the rear upper control arm forward bushing as 1in Aft of the suspension cradle rear mounting hole center. This will at least give me a starting point.

First things first, Can anyone confirm that I am interpreting the diagram correctly? If you think that I am incorrect, can you please clarify what datum "M" defines?

Next can anyone please tell me the following:

Are the rear suspension cradle mounting surfaces level to the ground?

What is the angle that the rear upper control mounting points are set to? In other words of you drew an imaginary line through the center lines of the rear upper control arm mounting bushings, what angle would this line be to the ground? It seems that it is very close to flat, approximately 1 deg off from flat.

I'd appreciate any info that you can provide. FYI, I have a build thread for my Camaro project on Pro-touring forums if your interested in seeing C5 suspension in a 1st gen fbody.

Hello. As someone who's done something similar (1970 nova on an 04 vette chassis) download "suspension analyzer" from Performance Trends. You get a free trial and the vette is one of the preloaded sample cars. You can get every measurement from that.
​Cool project. It's a ton of work but awesome when it's done.

Here's mine
