Rear Brake Decision

[Dillithium]

I have a dilemma I can't quite figure out, hope some of you can chime in.

 

I currently have a non c clip dana 35, it has a bad yoke that needs replacing. It has drum brakes.

 

I want disc brakes, as seen in my build thread I scored ZJ backing plates. These aren't a bolt on affair on non C clip axles, I don't want to mess with redrilling holes and adding a spacer plate. So I need a newer rear axle.

 

I forgot to check the gearing in my front diff last time I had it open, I'm assuming that with a 2.5 ax5 combo I have 4.10 in both diffs.(?)

 

Initially, I wanted a 29 spline 8.25 chrysler to put in the rear. Turns out that those axles are super hard to find with 4.10, and expensive.

 

Ford 8.8 is just not available in Holland, plus I would like to stick with a chrysler or Dana option.

 

My current thought, a c clip dana 35 is easier to find with 4.10. I already know where I can find one. I will never run tires bigger than 29-30", will never do more than mall crawling and DD'ing. A dana 35 should work for me. Also, if i'm correct I will not have to shorten my current driveshaft when I put in a c clip dana 35, correct?

 

Problem is, the JY could not tell me if the backing plates came off a V8 or the i6. I.e. dana 35 or 44a. Is there a difference in backing plates on rear axles for that? I can't find a reference picture anywhere. If they came from a dana 35, I believe it's a straight bolt on.

 

Bottomline, I really like the idea of swapping in a c clip dana 35 but I don't know if my backing plates will fit.

Also, if it turns out I have 3.55 gearing, there's an 8.25 waiting for me but I'd hate to have to spend money on driveshaft shortening and balancing.

never assume.  always check that ratio first :thumbsup:

Yes, I will have to in due time when I'm ready to swap axles. But does anyone know if there's a difference between the dana 44 and dana 35 backing plates off a ZJ? I can't find this anywhere.

This help? AFAIK the ZJ plates are the same from either axle, and the same as a D35 c-clip axle.

That's what I was hoping for, thank you Hornbrod! I'm going to try and figure out my gear ratio, then i'll post back the results.
