Can I use this to replace the unit on my SL-7700?

I know the description says SL-7800 only so just a long shot...

The fittings for both should be very similar but they're not listed as cross compatible by Shimano nor is this something we have ever tried so unfortunately would not be able to say for sure. We do however offer an entire set of the SL-7700 shifters for less than the cost of this one replacement part. These are SJSC part number 383.
