Pull any of the 12 back up distributors turn the engine as many times as you want and it will still be in time when you drop any of the distributors back in.
Katy is correct if we talk about other worn parts.

Ideally all will be OK, if you want to be on the safe side check.
One easy way is to check/set the points gap before putting the distributor in the motor, put dist. in the motor, fully retard the spark, set timing pin cylinder 1 TDC, and then use the Nurex Timing Wrench. It may not be 100 % fussy/correct, but is real close and is a quick check. The Nurex is especially useful for side of the road.
