Third member swaps

I have a nine inch with 28 spined axles, small bearing. Will any other nine inch third member bolt in? or does it have to be specific?

How do I confirm that I have a 9 and not the 9 3/8ths? Measure the housing im sure, but what part? I saw a couple at the junkyard in late 70s early 80s f150's those 9 as well?

I picked a complete 9" out of a '70 F100 (we think) and it's a perfect fit...

My girl talked the seller down to $70.00 while I was gettin' it ready
to load up!!!

11" drum brakes...BIG axle bearings...large tubes...we (and everyone)
have decided it is an "un-marked" Nodular...do NOT belive all the "stuff" ya
read about these things...

I have affectionately name this **** Franken-Nine due to all the headaches
I incurred tryin' to figure out what the he!! it is...

A 9" center section is a 9" center section is a 9" center
section is a 9" center section is a 9" center section...

The ONLY difference I found is some have a drain-plug and some do not...some fill-AND-drain-plug...weird huh...

You get the idea...
