Well, the tool as it sits will do the rear, as it's a 20mm rod. If the front is 3mm smaller, then the 17 mm adapter would be ideal. If the front is 17-18-19, you could turn the 20mm rod down to 17-18-19 and it will be fine. Then either use it that way, or shim it back to 20mm with duct tape, electrical tape, etc. when you did the rear. The tool also has a sleeve that shims the rod out to 25 mm. You could turn the 20mm rod down to 17 and still use it for the 20mm rear. I suspect it would work even with a little slop.
But you know what they say, " a guy can never have too many adapters....."
