I'm hoping someone here has experience with this one. My 79 K5 doesn't have a power steering pump, however it has all the lines for it. Previous owner did an engine swap, and failed to put the power steering pump in. I have a replacement pump for the small block 350, but I don't know for sure where the mounting holes are, nor what size bolts I'll need to mount it. Anybody got any ideas?

 

Go to a junkyard and get the brackets and all the hardware. You might have to look in quite a few being as old as it is. Here's a search engine you might try. I've used it on several occasions and it's worked well.

Yeah that's what I did. Just take all the brakets off a truck or montecarlo or similar v8. Bring a camera too so you remember how all the brackets go back together
