Here's my observations/some rough measurements:
OC6 SKETER
Front to back ( length to post center):
- 12 1/8" and 11 1/4"
Width F
- 2" and 3 7/16" F&R
Width R
- 2 7/8"
Mount offset F &R:
- 0 and 1/4" 0
Mounting holes on the towers for the post mounts are identical, both are 3/8" on center.
With an adapter plate you could modify the width settings in the Sketer up front to accommodate pre drilled bodies or you could cheat using the OC6 rear mounts and gain 1/2" in spacing side to side. At the rear you can also gain 1/2". The rear mounts are offset from the OC6.
As you can see the shock mounts are the defining factor the TC, especially up front. They are much close together compared to the wider chassis set up in the OC6.

Hey mate, throw up a link for those ARP parts. Are you using the bug bodies I've been seeing for the Nero chassis?
