8.25 vs. 8.75?

I wished I put my money in to an 8 3/4 axle years ago. I went with 3.91's in my 8 1/4 alxe and took the axle out and they cleaned , painted it. Cost $750 over 10 years ago. Now I'm stuck with the 3.91's, if I had an 8 3/4 I could easily remove the center and have different gears. Now I either have to drive the car 50 mins to my trans shop or worst yet remove the whole axle and lug it up there in a POS car.

So if you going to change axles why not get the better-easier to work on 8 3/4 ?
