OEM 12-bolt or new 9-inch?

[AALynch]

Hey guys,

I'm getting closer to ordering a 4-link set up for the rear of my 69 Camaro, and will likely be mini-tubbing at the same time...I've got an original 1969 12-bolt currently in the car, 1k miles on it, with 4.10's and a Tru-Trac. Is there any reason I NEED to upgrade to a 9-inch rather than getting new axles and C-clip eliminators for this 12-bolt and using it? It would certainly save some money, but I don't want to put money into the 12-bolt if a 9-inch is the way to go...

Thanks again!

Make sure you can get brakes that will work with those c clip eliminators. I know some rear discs will not.

Didn't even think of that...putting C5 brakes/rotors on it

No experience with it, but from what I hear the c-clip eliminators will leak if they are going around corners. They are designed for drag racing only. If it makes you feel any better I have a built 12 bolt with a tru-trac and moser axles and c-clips. Haven't driven it yet but I dont think it will give me much trouble. Maybe a little pad knockback if driven really hard but thats hard to avoid unless you go to a floater.

Strange Engineering, Morton Grove Illinois, introduces a new style, specifically designed for street and/or strip, c-clip eliminator for most 10 & 12-bolt GM car rear ends equipped with c-clip style axles. In the past, c-clip eliminators for these applications have been designed for drag racing, which use ball bearings. Ball bearing c-clip kits are fine for drag racing, but are prone to leaking and premature failure when used for prolonged street use. Our specially designed c-clip eliminator kit (A1033) utilizes Timken unit (tapered) bearings, which survive severe side loads and constant use.

The Strange A1033 also features two seals per axle shaft, ensuring a completely sealed axle end. Complete axle and c-clip eliminator packages are also available.

Nothing wrong with running your 12-bolt, however if you're looking to eliminate the c-clips, I would suggest that you consider just changing the housing ends and axles rather than consider a bolt-on c-clip eliminator kit. Anyone with the proper tools to narrow a housing should be able to weld on your choice of positively retained axle housing ends like the Moser #7750 (http://www.moserengineering.com/other-parts/housing-ends/big-ford-new-style-torino.html), #7800 (http://www.moserengineering.com/other-parts/housing-ends/big-ford-1-2-holes.html), #7900 (http://www.moserengineering.com/other-parts/housing-ends/c-clip-gm-car-uses-9-ford-large-bearing-and-non-c-clip-axles.html)(FM (http://www.moserengineering.com/other-parts/housing-ends/small-chevy-car-uses-9-ford-large-bearing-and-non-c-clip-axles.html)), etc.

In my opinion, for just a slight increase in cost versus bolt-on c-clip eliminator kits, you end up with all of the pros and none of the cons.
