Please take a look at the pictures of my intake manifold. I believe this is a 1975 302. In the pictures the previous owner used the holes to attach a chain for lifting the engine, but after I remove the chain what goes back in those holes, I don't think those are the original bolts. One is towards the front driver side, the other one is towards the back passenger side. They are circled in yellow. I got a number off of it D50E-9425-GA and found a picture on the Internet of one like it, here it is off the engine with the two bolt holes in question circled in yellow, can you guys tell me what goes in those holes?
