Blew the rearend out... now questions.

[CLASSIC87']

So Im looking at replacing the rear end... and checking out my options:
1. What years interchange with my 87' as a DIRECT swap, would the 89' pictured below work?

This just hasppened Friday so I haven't had time to take measurements, look into details, etc..

Thanks,
Anthony

I would stick with the 73-87 trucks or 73-91 2wd 'burbs for a source.
Is that rearend out of an '89 pickup? If so I would say it's different.

Sorry to hear about the rear Anthony. I think now is the time to build a rear with a posi and a little gear . As to the 88 up rears , I am pretty sure they are a little wider from mounting flange to flange which might cause problems with the wheel clearance and the leaf spring perches are a different width .

Cool, that should be a good upgrade.

Sorry to hear this news , I love your truck and would love to own it , with that said I would not jump to any major decision about replacing the whole housing , Get it home , jack it up , take the rear cover off and inspect what happened. You might be surprised , might just be a broken spider gear or something minor.

Your truck should have an 8.5 rear , which for what your doing should be fine , Let me know what you need for parts and I can walk you through any repair , I will be glad to help....

Sorry to hear about your truck. It's sad to see such a nice truck being towed away. I think f. monroe is correct about the overall length of the differential being wider. You could always upgrade to a 12 bolt rearend. It's a direct swap but you have to change the u joint and shaft end.

Awesome guys... thanks for all the info. Im not going to be able to go all out with it right now (received my lay-off papers Friday as well) LOL... but its all good- I'm going to have the time to work on it!
I did come accross a new Eaton Posi carrier? on Sat for a $150 if I end up going that route. Early in the game... hoping to tear into it on Monday in my dads pit.

anthony,rephrase that about old freinds and your rear end would ya,your scarin me............if you'd keep your foot out of it.that wouldn't happen
glad to hear your gettin off cheap.......leave's you more play money at the casino

[Driveway Dreams]

Great to hear. That should be fun. I hope to be able to find a taller gear for mine to help offset the 3 speed in it. I put the 12 bolt in from a 77 Burb which was a simple swap, just had to get an adaptive u-joint. Not bad though. Cheaper than a new shaft.

[pcmcobra]

let us know how it goes..

[Captkaos]

You will need a conversion joint so this will be a bolt in.
there is no upgrade going from 10b to 12b though. 10b had more splines on the axles and larger pinion shaft..

Correct-O... I actually recieved a call from him yesterday saying that the Posi unit that I picked up the other day from another friend will not work. So I will be going with the standard rearend with a 373... will be back on the road by the weekend.
