What brand R&P gears to use for a rebuild?

When I had my 8 1/4 rebuilt I went top notch and got Richman 3.91's, that was 14 years ago and tons of mileage on them now--least 50,000, I put on 3,000--4,000 miles a year and have cut way down as gas prices have gone up, when gas was under $2 I was racking up the mileage

Never thought I have it this long but sure glad I got the best gears I could get for it, would stink for them to break
