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?
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.
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.
