C5 torque tube bolt pattern
 

Anyone have a drawing or cad or the bolt pattern that goes between the torque tube and engine bellhousing for a C5?

My brother and I have a C5 torque tube and trans for our project, but unfortunately we don't have the right tools for accurately measuring the bolt pattern. I've tried measuring it with calipers, but I can't seem to make sense of it. I don't quite trust the current pattern drawing I have.

Alternate solution: Anyone with a C5 bellhousing that would be willing to throw it on a flat bad scanner with a steel ruler?

Thanks guys!

Layout the pattern as best you can then print it out one to one scale to check.

Thanks for the tip, but unfortunately, I tried that already and did one better. I machined the pattern I have in to a scrap of aluminum, but it didn't match closely enough to satisfy me. I don't want to have to fudge this, which is why I'd like something I can take more precise measurements off of. The holes in the torque tube are either conical or don't have decent surfaces to register off of.

Ironworks has some CAD of the torque tube and corvette suspension, I think I remeber seing a thread where the post the CAD. Shoot roger a PM and see if he can share the bolt pattern.

Thanks for the tip, Bryce. I sent Ironworks a PM and he said he would try to find it. Anyone else sitting on what I might need?
