The M/T out of your 85 needs to be out of an EFi vehicle too. That would be the W series. If it's carbed, that's the G series, and I'm almost positive it's a different bellhousing to M/T mounting pattern.
As for wiring, you'll still need the complete wiring harness(es) out of your donor car, then just splicing in. (Ignition, charging, etc.)
