Is it worth keeping the Olds 10 bolt that came with the metric Cutlass I'm working on, or should I get a rear end with the c-clips? Is there anything that can be done to make the Olds rearend usable? It just seems to me that the pressed on bearings would be stronger than the c-clips. Any help would be appreciated. Thanks...loojack

i had the 10 bolt with the bolt in axles and had nothing but bad luck the flange on the axle kept breaking off if you use it make sure you reinforce the plates that bolt the axle in with 1/4 inch flat steel, i went to the 10 bolt 8.5 ring gear with the c clip type and never had a problem after that also if you use that bolt in axle take them out every 2 weeks and have them magnafluxed to be safe

That I didn't know. It is a metric axel that came with the car('79 Cutlass) I have a book, a Haynes manual, that says that rear axels with a B (Buick) or O (olds)in the code stamped on the housing, didn't have c-clips. I guess I should open it up and see. Thanks, loojack

the bop rears we're bolt in before 1970 i'm not aware of any after that make sure you spot weld the bearing on drivers side to keep it in,bolt in axles aren't necessarily bad 9" fords are bolt in and they are supposed to be the best.

I like the c-clip...It seems to be stonger.. [IMG]http://www.thedirtforum.com/ubb/smilies/cwm 35.gif[/IMG] on the c-clip rear end I use I have never broke an axle at the clip area..I only broke them at the hub part and it has only 3 axles do to cliping the wall...

I ran the bolt in style for 2 years. The recommendation about the 1/4 plate is excellant. I made some half moon clips that went on the outside flange (bearing retainer) to beef it up after the flanges started to give a little. Overall it is a safer rearend than the c clip style but the parts are harder to find, and the bearings are ridicuolously high. Another drawback to the boltin is to replace the seal you have to replace the bearing also. If you already have it use it. Just so you know, the carriers and gears out of the c clip style will work in your rearend.

I'm running a bolt in too. It's factory in my 73 Cutlass. I replaced all bearings and fragged the passenger side in the first race. ( My fault??). I bought a salvage axle for 20 bux slapped it in old seal and all. It ran the rest of the year. I've seen several c-clip axles rolling down the track like a steel joust. Not to say one is worse than the other, though. I am going to add the plates to mine, thanks for the tip.

A few nice things about the bolt in axles are if you break an axle it does not leave with the wheel. And also if you bend a flange the axle can be replaced without swimming in gear oil!
