Definitely not going to make this up on economy, but dropping the RPM's and postponing rebuild / preventing engine failure makes total $$ sense.
Plus our next trip is across Texas, New Mexico, Arizona and Nevada in August...definitely want to keep the heat load down and run the speed limit.
I did mine myself. cost me $307 for a set of 3.58 gears for my RR20-145 rear axle. paid a buddy of mine $100 to help me set them up right.
It took me about 20 mins to make a bracket so i could mount the center casting on a engine stand. (Makes it much easier that wrestling that thing on the ground) I bought my gears from Anderson bros in Portland, they are axle rebuilders. the gears I bought were even re parkerized.
My Ford had a set 5.29 gears in it when I bought it. Without a OD I was some where around 55 MPH for a top speed.

Mine has paid for its self. I'm sure of it.
