Will RCK60-27BA mid-mower interchange with RCK60-24B I have now?

[Bob_Young]

I have a B7610 with a RCK60-24B mid mount mower that's been used extensively for 17 yrs and is in need of an overhaul (the gauge wheels all look bad). A lightly used RCK60-27BA has come up on craigslist nearby. It looks exactly like mine but dimensions could be different. It was originally on a B3200. Would like to have two mower decks that interchange.

Does anyone know what the differences are between the -24B version and the -27BA?
