440 cu in w-A/C need idler pulley and roller

[retro70]

Hi, I am looking for an idler pulley and a roller to install on a 440 cu in 4bbl that has air conditioning installed already. The PO did not know that these were used with his A/C so he threw them away in the scrap heap and now I need to find them somewhere to complete my install for A/C on my 1970 Plymouth Barracuda.

BTW, if you have the docs for this year car, you can find these in the pictures on page 9 of the cooling section.
Thanks Dennis

P.S. I will take the parts numbers to these if you have that.
