Engine bolt pattern?
 

Hi there!

I need to know dimensions of eninge-to-transmission bolt pattern. As far as i know, almost all 911 SC/930/964 have same pattern towards transmission.

I need to know if they are spaced exactly 90 degrees from each other, diameter and if output axle is exactly in the middle of "circle" whose circumference bolts are on.

It's for our engine-adapter.

Anyone?

This probably doesn't help but I know the left side and the right side bolts have the same spacing. In other words, you can bolt either case half to the engine stand/yoke.

Yupp...Mattias measured holes on the tranny and as far as we know, there are four of them and they are at the same distance from input-shaft. Actually, it seems that they are just four concentric holes...that makes things somewhat easier.
