Does anyone have a link to a site with the bolt pattern dimensions listed. Or rear of block dimensions. I'm looking to make an adapter for a GM tranny to a non-GM engine. So, I need the GM info. So, I'm looking for actual dimensions off a blueprint.

I know somone knows where to find it. I've only found MOPAR stuff so far, which was a blueprint of the bellhousing. Looking for the same thing only for GM blocks/trannies. And no, I'm not adapting a MOPAR to the tranny.

Thanks,
Nick
