Rebuild 904 or swap for 727?

Pretty much a guarantee that they will tell you what they will use. You start telling them you want this or that they’re likely to recommend you do it yourself or you better be prepared to explain to them why you think you need x, y and/or z when they may say you don’t, that they do things their way. Just a touch of reality here, I’d theorize most shops are going to use what they like to use.

Have you looked at what it would cost to change the slip yoke, differential yoke, have a new driveshaft fabricated with new yokes etc?? Just wondering: why are you thinking that you might need to swap out the 7260 yokes/u-joints?
Its your money, but the 7260 setup will be all you will ever need. I’d spend that cash on the converter.

I first asked that question because I was always under the impression that the 7260 joints were smaller and thereby weaker. I have since heard from several people that they will be fine for my setup. I will just have the 904 rebuilt and keep the same driveshaft and yokes with new 7260 joints.
