Default Muncie 4 speed shift forks

Is there a difference in the 1-2nd and 3-4th shift forks in a Muncie 4 speed? If there is what is the difference and which fork goes on what gear?

Not the best pic for comparison, but they are the same.

I noticed a fat side and a skinny side , can they be 180 out or does it matter. The reason for asking is I rebuilt my 4 speed, new synchros, bearings and seals. Shifts ok but from time to time it has a hard spot halfway into 1st, like it hangs but will go in with a little more pressure. Trans may need a little more break in time.

Muncie shift forks are 100% identical, NO up, down, left, right. Can't say it any clearer.

That pic creates a bit of an optical illusion - as Tom says, no up, down, left or right. Another pic showing forks (in circle) disassembled.
