Need help assembling 1989 engine horseshoe bracket

[TruckNorris89]

My son and I are working on a 1989 K1500 single cab, short bed as a project for his first truck.  We took the OEM engine out over a year ago and I goofed up and didn't take enough pictures of the horseshoe bracket as we disassembled the front of the engine.  We're putting things back together now and we have 5 brackets that we just can't figure out there they go (picture attached).  I'd appreciate any help you can give to ID these brackets and tell me where they should go.  If you have any pictures it would be a huge help.

 

The truck is a 5.7L TBI without a smog pump.

 

Thanks,

KJ

The triangle ones are for motor mount to tranny

Thanks for the info on the Triangle brackets.  We already have the block installed and hooked up the tranny.  Are these brackets critical enough that I need to lift it back up and install them?

I finally figured out the long brackets are supports for the AC compressor and Alternator that extend from ta stud in the middle of the intake to the back of each.   The small goofy shaped bracket went on the under side of the AC compressor.

 

Lesson learned......take more pictures than you think you'll need!!!!! 

 

On a hugely positive note....everything is back together and she runs great.  We took the first drive on it's own power and my son was grinning ear to ear.
