My 55.2 3100 3 speed trans has a 4 bolt side cover with one shift arm up and one shift arm down. 56 up has both shift arms down. So my question, is my side cover set up a one year only, or can I get a cover from and older truck that will fit (work) with my three speed?

The one up-one down setup was used on ADs. I'm surprised '55 second used it.

55.2 uses it because of the configuration of the shift rods that use an intermediate pivot point, the 4 bolt covers are all the same, but the linkage movement is different so the arms face different - was changed for '56 to eliminate that intermediate bellcrank pivot

So would it be safe to say that if I changed the pivot rod set up, and got a 2nd-3rd 1 piece rod, I could use a 56 and up trans with both shift arms facing down?

You can use the side cover from an earlier truck on your trans since they both have the up/down configuration.
However, you will need to use the L/R shift fork from the TF side cover as the shift fork on the AD trans is narrower to accommodate the narrower slider gear.

You can also use the 56 side cover and the one piece rod.
56 up (and 55 V-8's) used a different shifter box to allow clearance for the V-8 exhaust manifold. This should not be an issue with the 235.
