Stop in for a cup of coffee

For the 87 318 engine in a 88 ram with ac.

My son converted his 71 Val to non-A/C. I'm not sure where he put his stock pulley, but I have a "stash" of them in a box that I sort through when I set up an engine...

I'm not sure if the 71 pulley is the same as the 88 one...

What about looking on www.car-parts.com for one???
