Those are 6 cyl. support brackets. That is why they don't fit or reach. It is hard to tell but I'm pretty sure from your second picture you have the right plates that mount from the frame to the rubber mount. You Just need to get the v-8 support brackets jack the motor and install.

Thanks Barnbird.
I believe the the top plates that sit on the engine cradle look correct .
Doesn't look like i can purchase those missing support brackets separately? I have to buy the whole 4 piece set.
Also question on my pinion seal. Advance auto shows one type without the flange and Ames shows another like this with the flange.
Which one do i need?

Post and get some used ones, not a high dollar rare item. Yes the seal has a flange.

Diaphragm going bad in pump. This is another reason to check your oil often, you don't have to taste it but you should be sniffing it to catch before it ruins seals and or motor.

thanks Barnbird,
I just can't wrap my head around how a pump that is external and pumps gas externally up to the carb could get into the oil pan. I do understand fuel pumps go bad

Should I assume mine is bad and buy a replacement or is there a way to test mine out? I Can't run the motor yet

One side of the diaphragm sits on the oil side where a fulcrum ( powered by the cam) pushes the diaphragm up and down. It the diaphragm leaks, gas flows from the gas side to the oil side. Happens more often than you want to know.

Thanks hokie for the clear explanation. That is very disturbing to find out.

Am i better off converting to an electric fuel pump?

Does it matter what kind of replacement mechanical pump i might buy?

If I pull the fuel pump off the block will I be able to tell if gas is getting up in there?

Didn’t mean to scare you because it doesn’t happen that often, but you should be aware of the symptoms. If it was me I would put in a newer mechanical pump designed to work on today’s fuels. No real need to go electric.

Any recommendations on a mechanical pump?

I saw so many options and prices out there.

What are the symptoms besides gas in the oil?

Hey Barbird,
Every time I try to order a pinion seal the one with the flange always says for 12 bolt and the one without a flange is for the ten bolt.

I know you said I need the one with the flange but they are clearly different sizes and I need to get the right one.
thanks

Well the drivers side rotted header came off without a fight. (not counting the impossible to get at bolts) To get the replacement in will be a different story
