Ford 7.5 2.26 ratio, custom grind or used

[gearguts]

Ladies and Gentlemen,  I have been searching for the elusive 2.26 ratio ring and pinion for the ford 7.5". Finding used has so far been fruitless. I will keep looking but in the meantime what sort of experiences have been had by those of you who are running custom gears, if any ? Things like cost, quality and noise, maybe some input on durability/longevity ? Any leads or recommendations are much appreciated
