A833 main case hole pattern PCD, casting SBM/6 bell housing New Zealand

Hi Team,

I have found a casting/tool maker to make a bell housing for me, I was going to get a lakeside and weld the hole and mirror it on the other side (New Zealand RHD) but the only hole pattern is SBM

I had a look to find a template on here and Google but no such luck, I was hoping someone on here may have the dimensions, also looked on the brewer's website

Also, the mounting pattern for an SBM and a slant 6, is not so important as I have a 3-speed slant 6 bell housing to work off and a 727 bell housing for the SBM but it would be well useful

Attached is an RHD bell housing for a laugh LOL and the size of the bearing retainer in metric :-) this is the 4.354" DIAMETER? 110mm to an inch is 4.33071

We've got both a slant 6 and a SBM here and we are trying to make a dual mount for the bell housing, has anyone ever done this? I'm hoping the length of the input shaft between a SBM and a 6 is the same. (8.625")

Any help, chats or pictures would be appreciated, Chris from New Zealand
