chevy bolt pattern :thankyou:

Honestly if you want to do that many upgrades you might be better off selling your factor 12 and buy a built Moser 12. That way you can do 33 spline, posi, new gears, axles and special hosing ends.

If you go this route, be sure to specify the 7900FM (flush mount) so your seal sits flush. That way you can use your brake backing plate as the retainer.

It really isn't that hard to put new ends on your axle housing. You already know the width that works so as long as the ends that Vince recommended will mount your brakes then you just need a long 1.25 inch bar and some adapters to hold everything straight. I don't know about you but narrowing the rearend was one of those bucket-list things for me. I am pretty happy I did it. I will loan you my adapters after I am done finish welding if you want to tackle it. The bar is just ground and polished shafting from the Inter-Web. The outer adapters have a 3.15" and a 2.84" shoulder. I think that covers the large Ford and the Chevy 12-bolt diameters. Here is a photo in-process.

You probably need a pinion center finding tool also. I could loan you the one I bought from Moser. I is really well made.

The pinion is 1/2 inch to the passenger side. All the axle companies are really good at answering questions if you get unsure about something.

I will get ahold of Moser and find out what I need for the Ford ends with tapered bearings and retainer that will accept my Wilwoods. I saw your update with the rear shot .... NICE!

Thanks for the offer, I will get back to you .....

if you have a Chevy bolt pattern brake set up the Moser 7900FM is the ends you will need. It features a Chevy bolt pattern flange and houses a large Ford Bearing.

Vince .... thanks for the link, it should be Chevy ends but I'll check the upper and lower bolt measurements before I call Moser.

I appreciate the info from the guys that have done this before me ... Thanks.

A Miracle
 

does happen, I uncovered my 12 bolt from all the plastic bags I taped on it three years ago and whala .... I hit the jackpot w this 12 bolt I bought. The seller had it under his Firebird and said it was professionally rebuilt and never even had gear oil in it, he was correct.

Take a look ... I think I'm ready to go, gonna take off the perches and prep it for the Ride Tech air bar install, its on order now, I'm totally stoked (if you couldn't tell!).

I do appreciate all the comments but, .... for the price I paid for this 12 bolt I'm keeping it fer sure, not sure what size spline the axles are.

She'll do fine under my Camaro.

Thanks for looking ....

Looks like it has an aftermarket ends already. They appear to to be Moser...at least they look like the Moser 12 bolt I have at the shop. see picture at post 11

Pop out the center shaft and see if it has c-clips.

What did you end up doing? I have a 12 bolt 1970 camaro rear with Mark Williams c-clip eliminators and drums. Wanting to run disk brakes bad but having trouble finding some other then the non popular TA 12 bolt disk brakes setup. Does anyone know if the s10 disk brake swap could work?

Depends on your budget.... You can hack the ends off and go to a full Floater set up with Corvette hubs and brakes
