BBC into a 66 K10

[argonaut]

I've been searching and searching to see if anyone has a build thread documenting this swap already. I've seen a few on 64-66 c10 trucks, and some on 67-72 K5/K10s but don't think I've seen one on a 60-66 K10.

I want to keep the drivetrain locations the same, so I need the motor mount brackets to accommodate this. it is unclear whether there are some factory brackets that I can make work for this, or if there are some aftermarket options. It doesn't look like the aftermarket late model tubular type mount brackets will bolt to the 4x4 crossmember.

Any thoughts, ideas, pictures?

Thanks.
