Does anyone have any links for the factory C4 IRS suspension geometry?

It would be greatly appreciated.

I know I can get a shop manual. I was just hoping there was a suspension (how-to) for the C4 out there somewhere.

I have fabricated the rear frame section for my 50 Merc to use a C4 IRS and I have installed a kit from Flat-Out Engineering to use a C4 IRS on my 56 F100. What specific geometry were you looking for? I have some Visio drawings that I worked up for both the IFS and the IRS if you need them.

I appreciate it. I got the information I was needing from a thread I made later. I was told 3-4 degrees for the propeller shafts, and I "think" he said dog bone front braket set at a 60 degree angle from 90. Off the top of my head I can't remember exactly what he said....but I made a copy and have it in my build folder at work. Do those angles sound right? I'd appreciate those drawings. They might help as I still have to cut and modify my frame. I have a good idea of what to do now....but any thoughts would be appreciated.

Thanks,
Dave
