68 Barracuda F/B rear seat parts wanted

Hey fellow Moparites!

looking for the following parts for my 68 Cuda fastback Resto.
1. left and right seat back release cams
2. return spring for seat back release latch
3. plastic flange bushings that seat cams fit into.

I'm in Eastern Canada (NFLD) and everything is almost impossible to find here.

Any one on here that can help me out???

Thanks guys and Gals
