I'm kinda confused here. My uncle and I were trying to get the ol 56 tbird running today and we were having trouble getting the oil pump primed up tothe heads. Long story short the melling is-42 drive shaft appears to be too short. It's 8 inches long. Why would the standard shaft be too short?

I nok w believe I need an is-60a which is 9.1 inchs. ?
I was able to make the pump work using a long apex extension which pushed oil out the oil filter hole.

Also if anyone knows where I can buy a throttle linkage to attach an edelbrock 500cfm carburetor to the bell crank assembly? Mine is a bit too short.

lots of people are having trouble with replacement distributors being to short not the shaft.check yours against the old one.
 
Ah I'm an idiot lol. I see now that the distributor looks like it has a socket that sticks out below the gear.

I was trying to get a 1/4 in apex on it to try and pre pump oil through the engine before installing the distributor.

I need to pull the oil pump and install the drive from below 😆
