Ford 9" advice
Hello Everybody,
I have a basket case '77 that I'm turning into a Bonneville Racer, so I'm basically gutting it.
I'm looking at a complete rear end rebuild, trailing arms, half shafts, missing clip on an axle shaft, everything very rusty.
A friend suggested replacing with something else like a 9"
Anybody done this ? I've searched,
Advice ???
Thanks, Frank

C3 of Year Finalist (track prepared) 2019
There are a couple of people who have done similar, and I believe there's a kit available for fitting a solid rear axle. As above, the c3 is not a very aerodynamic choice for Bonneville. Also, a Ford 9" consumes quite a few hp, you'd probably be better off with a different rear end (Borg Warner perhaps?) that would sap less power, particularly given strength is going to be much less of an issue in a Bonneville car, as there's nowhere near the shock loading it would see on a drag strip or even race circuit.

In light of replacing every part of the IRS and the fact your going in a straight line TOSS that junk ..
A 9" to someone with power is the holy grail and to those who dont have power misunderstood .
Auto Fab makes the 4 link kit , You can buy a used axle and carrier and fab it up. And it will be affordable .

2021 C1 of the Year Finalist - Modified
A Ford 9" would be my 1st choice for such a project. They are easy to set up and there are a ton of diff gear ratios available. What class are you thinking? Good luck, sounds like a great project.

Ha - the one in my avatar went 137 - they won't give you a timing slip if you go 140 or beyond with out the required safety equipment.
I agree it's no speedster it was capable of more, but you need a roll cage for the 150 club. I bought that car new in 77 and did not want to cut it up for the modifications needed. So I rescued the current one and will give it a go.
When I get it there you can come for a ride -

The one in my avatar is in the 130 club (137 average - 2 runs ) 150 needs a roll cage, I didn't what to cut up that one as I bought it new. It has an LS1 with T56.
The one I'm working on will have a de-stroked 454 ( I always wanted a 427 ) and didn't want to fake it. I'm still deciding on the trans.
Thanks, Frank

On the topic of Ford 9' rears,
Can you extend a Ford 9" rear end?
Meaning go from a full tub set up to more of mini tub. I don't care for the pro street set up and would rather have the axles extended to accomodate some 335/345 size tires.
This is currently in a c3 Vette.
Thanks,

Or you could have Bubba weld extensions on to the ones you have.
I don't recommend this.

I will have to go read yer bio if you got info about yer Vette.
No, I never got along with Bubba and will not go that route.
So the diffy will pull from the tubes/axl housings and you can just get them to right size? I will obvioulsy need longer axles though.
