'71 220D gearing

Hi all. I'm new here, and soon to be a proud MB owner. This coming summer I will be picking up my late grandmothers '71 220D and driving it cross-country (roughly 2500-3000 miles) to its new home.
It is a well-maintained 4-speed car, with the engine professionally overhauled not too long ago, so I am not worried about the car making it. But, I would like some way to reduce the RPM's for the long highway miles. My research has found that the axle ratio on this car should be 3.92:1, and with the 1:1 top gear in the tranny, gives only 80mph at the governor.
Is there a Mercedes 5-speed overdrive (manual trans) out there that I could slip under this car? Is there a 5-sp from some other manufacturer that would work? Or, should I just go for a new axle ratio? How hard is it to change the rearend gears in these cars?
