I need help with a lot of stuff...

I recently bought a 1965 Plymouth Valiant. It has a 273 cudda commando motor in it and was converted to automatic. It still has the pedals in it though and was a floor shifter to start. The parts I'm missing is the mechanical linkage and I'm not entirely sure what will be needed to switch it back to manual transmission.
I also like the look of the dart front styling over the Plymouth. I am wondering what parts will I need to switch to get the 65 dart front grille on there? Will I need the whole front cip, or do you guys know if I can just get the grille and swap it out?
I want to apologize for my writing skills and I hope this whole thing makes sense to whoever is reading it. Any help sourcing parts, or just hands on knowledge of these vehicles will be a great help to me.
Thank you for your time,
DaValCudda.
First off don’t worry about your writing skills as much as posting pictures. We want to see pictures, and if there’s any parts that you need post here.
