1983 Olds V8 5.0L 307ci Fuel Pump Eccentric and Camshaft Bolt and button and Spring

My tata has a 1965 Oldsmobile Delta 88 with a 1983 Olds V8 5.0L 307ci inside and he is currently rebuilding it.

He is missing the Fuel Pump Eccentric and Camshaft Bolt that goes with it and also the Camshaft button and spring.

He needs the whole assembly if anyone has it in their collection or can help us with some pointer definitely let us know thank you for taking the time to read this and your consideration.

First I've heard of a button and spring on an 83 307. Those had flat tappet cams and never came with that. Roller-cam engines from 85-90 had those.

'83 Olds 307ci Fuel Pump Eccentric and Camshaft Bolt

As stated above, never heard of those on an '83 307. That being said, I do have fuel pump eccentrics and the special bolt that holds it to the front of the camshaft. Please let me know if you're interested. Thanks, Bob.

I see that I am mistaken, me and tata were watching a video on YouTube of someone replacing the fuel pump ecentric on a Oldsmobile V8 and just assumed that we needed one, after further research we now see it doesn't take one.
