Re: Do all SM465 have the exact same trans-to-bellhousing bolt pattern?

Thank you MJN and Leon, I was actually a little worried because my bellhousing on the truck is cast iron and this one is aluminum and I was afraid it wasn't the same.
Thanks for the info; I'm a little surprised that such a heavy trans was hung from an aluminum bell...
