Need Part Numbers ASAP

I need an oil pressure sending unit that will work with the `68 `Cuda's dash gauge. The one I have is starting to leak. My local Chrysler parts dept. mentioned that there are several choices for the later 360.
What should I be looking for? :scratch:

Also I need to know the difference between a stock throttle cable and a six pack one.... Is this BS advertising, or is there a specfic one for my intake? :?:
I want to replace my old, original cable before it goes tits-up.... :bom:

And BTW, if anyone has a six pack throttle cable bracket they want to sell....

Thanks in advance guys ! :thumrigh:
