Helmet modification for IMCO SC drive

Was curious if any once had any detailed information in regards to modifying my helmet in my ITS transom for a IMCO SC drive. Looks like the lower profile of the IMCO helmet has a bit of a different profile to account for the oil line running from upper to lower. If anyone has this helmet could you post up some dimensions ? it looks like just trimming off the lower bravo lip but was not sure if they started life as the same casting.

Yes, had to notch out helmet before the imco drive would fit properly.

Is it as simple as trimming where I drew the line? or does it need to be more contorted ?

Yes, that simple. I just cut off the right half below your line.
