If the front shifter is friction, you can probably get away with throwing any two rings of the previous tooth-counts together. My rando bike used to feature a "9-speed" Shimano 50T and "6/7/8-speed" Sugino 38T on a 6-speed crank to good results. Now it's a pair of 9- or 10-speed Sugino (XD700?) rings on a different 6-speed era crank. An 8-speed chain ties it all together.
