Help needed : fitting a 930 flywheel onto a 3.2

I'm now trying to install a 930 SBH transmission into my 3.2 Carrera engine (part of a turbo project), but I found that the original flywheel has a dowel pin hole to match the one on the crank, but the 930 flywheel don't have that, am I missing something here? .. I tried to browse some 930 images on the web and I see none of them has the dowel pin hole. And if I just pulled the pin on the crank and install the flywheel, will it be balanced anyway I fit it?

Ok, I just found that the holes will match only one way, but now I can't get that #$#$ pin out of the crankshaft!

I ran into flywheel fitment problem also for my 930. Turned out they changed flywheels during the year. Forgot if I needed later or earlier.

The flywheel pin is superfluous
If you’re running moronic you’ll need a TDC marker on the edge of the flywheel, plus cogs
The G50 flywheel can give you the good stack and motioning
The pilot bearing is the big difference between flywheels
