I agree with Gus about the belt or fluid.

Hmm, if it is a Chebby it would be a 67 or 68, they moved the alternator to the right side in 69. Power steering bracket looks quite a bit like the Pontiac 68 hard to tell though. Would only have to look at the two cylinder heads. Pontiac has the right side, passenger, mounted forward of the left side, Chebby has the left side mounted forward of the right.

I'm sure Misema knows what it is.
