up through 9 speeds, the RD pull ratios are the same between road and MTB groups.
The FD pull ratios are different. But back in the 7 speed era, Shimano typically used a friction shifter on the left. Only the right shifter had indexing. Like these Deore shifters:


These should work fine for the OP
