Basically, the transmission output shaft (lose the extension housing) and the tranny to transfer case adaptor. While you're in there, make darned sure that the reverse piston and stack has the 5 fiber setup. Many Cameros used a 4 disc setup, but behind a 350, you should be okay.

Also, check the loom for the converter lockup feed, the brake switch and possibly the PROM in the ECM may have to be changed.

The dipstick/tube and throttle cable/bracket "should" interchange.

Think long and hard about this tho, as any 4L60 older than a '91 is a meltdown just waiting to happen. GM didn't get this guy perfected until 1991.
