not to steal the thread but i have a slant in my 68 dart (street,strip) thats at 200hp soon to be more like 300hp, also redoing the stock 904 with 4200 stall and manual valve body. so i have an 8.75 741 case 3.91 gear set up, just need axles and 742 case. so my questions are
what axles/bearing do i need for my hp and conditions
also do the posi's swap from a 741 to a 742,489??
thx guys
sweet thank you i would but they are expensive lol
Green bearings suck for a street car. They don't handle sideload very well.Less drag for racing, but on a street car they will not last long.
You can use axles from a big C body and have them shortened and resplined. Would be alot safter then re-drilled if you are putting down alot of power. Also don't forget about your brakes. The offset on the axle flange is different from stansdard A body 8 3/4 to allow for those narrow brakes. I think you can get aftermarket done both ways. I am using C body axles shortend and resplined along with the brakes.
I have a set of axles and complete brake plates including e-brake cables in very good shape for $100.00 plus shipping. Everything came from a 70 340 car.

I don't believe much of what I read,but I know bearings very well. I have been working with them for over 20 years.If you read the technical data and failure rates of tapered and ball bearings you will find that in this application the tapered bearing is far more durable.I have discused this with my driveline guy, who has been a Mopar driveline specialist for many years, and he agrees with me. It seems I have offended some and that was not my intention. I do not wish to debate this nor do I wish to dispute the success others have had with with the green bearings. I apologize and will choose my words more carefully in the future.
let me see about a housing first. youra are a body length? and bbp? if so i will probably take them

why is this goin so cheap and no one is bidding lol? the round part on the back looks different then most 8 3/4s but idk if that would matter. i could make a new of that part if i need to but will this work lol?
As long as it's a 5 x 4.5 pattern, the brakes swap from rear to rear, no issue.
8.25, 8.75, 9.25, Dana 60 They all interchange and the drum are specific to the backing plates, so keep them as a unit. Sometimes you have to drill a 5th hole in the backing plate where it mounts to the flange.
