could someone please post a blow up for me before i dive in blind

I've looked for something specific to the 35 120 pump but didn't find it. But what's the reason you want to "dive in"? I suspect that pump is essentially the same as used on the junior cars thru 39 and all the L-head eights thru 1954. Two spur gears, cover plate, and pressure relief valve. Oil pumps seldom need service on that type of engine, so what kind of problem are you experiencing?

This is a 51-54 pump. But basically the same.

prety sour oil pressure after warmed up 10psi. was hoping to possibly shim the relief spring. but am hearing 35 was no relief spring. i just wanted to see how many gaskets i may destroy as well

thnks for the info

Not a very exciting picture from the 35-120 technical manual. My earlier comment suggested if you have the original pump on the car, it does not have the "updated" pump cover with the pressure relief spring, which was the factory replacement part, common in design to nearly all Packards, and other car manufacturers, of the period. If you think its the oil pump itself, I highly recommend you find and install the "later" version. Not a hard part to find...
And no, I have not forgotten about your inquiry re:tie rod end modern number.
