Gears & Axles - HELP! 12 bolt backing plates core?

who makes them and ships them out the FASTEST? I really want to buy a 12 bolt for my T/A, I plan on ordering one this week, is there ANYONE who sells them without needing my brake backing plates or axles sent to them?

I don't want the down time of sending them my brake backing plates and or axles.
A local speed shop makes 12 bolts for $2650 plus $300 core charge on the backing plates! thats with 33 splines/eton posi/any ratio gear/ta girdle good deal?

Have you talk to Jason on EFA?

slp sells one for 2505 shipped (last I checked), same stuff. But the webpage says 6 week delivery.

Check T Byrne's website. I think he can get you a 12 bolt cheaper with backing plates.

it says in the ad on tbyrne that they need the brake backing plates sent in a week before they ship the rear end.

I bought this shop press (http://www.harborfreight.com/cpi/ctaf/Displayitem.taf?itemnumber=32879) a few years ago when it was on sale (which it does go on sale occasionally). I used it to press the bearings on to my 12-bolt axles - and used my existing backing plates. <img src="gr_stretch.gif" border="0"> So, if you have your own shop press, no need for extra backing plates. <img src="gr_images/icons/wink.gif" border="0"> They're quite handy to have laying around the house.

And $2600 + $300 core for backing plates? Yikes. I ordered my Moser from Thunder Racing for significantly less than that, and did the final backing plate assembly myself... It was easy. <img src="gr_stretch.gif" border="0">

You can order your rear end from www.ragingmotorsports.com (http://www.ragingmotorsports.com) for ALOT cheaper and you dont have to send in your backing plates. Should be about $2300 for all you listed. And you can use your own backing plates when you swap the rears. Anybody with a press can hook you up in no time. All they are doing is pressing bearings onto the azles... <img src="graemlins/formula.gif" border="0" alt="[Pontiac]" />

hmmm thunder shows the 12 bolts available in 2-3 days plus shipping time!

if I get it and install the backing plates myself, HOW do I do it? can I get a local auto place to do it? do I simply press the backing plate onto the axle then slide the axle in?

I don't get it if all that needs done is bearings pressed onto the axles why do they have to wait for brake backing plates to press them on????

do the backing plates go between the bearings and the axles?

if I buy mine like this will I have to do anything with the gears? Or just install my backing plates, press the bearings onto the axles and slide the axles in?
what holds the axles in.

THANKS FOR ANY INFO!
this may save me $300 to go this route through thunder racing!!

I got my 12-bolt in under two weeks, for sure. I think it may have been like 10 days total, including shipping and weekends.

As for how the bearings / axles are set up, first you slide the backing plate on to the axle, then the bearing, and then the press bushing (it accompanies the bearing - so that you're not actually pushing on the bearing itself). Insert in to press, push until the bearing is flush with the shoulder that it goes against. The backing plate now sits between the axle flange and the bearing. The press bushing gets pressed on there too and stays, but doesn't really do anything.

You can get backing plates from GM dealers for ~$120 or so (not sure if that's each or for both, I'd imagine each).

I'd bet if you can find a shop with a press, it wouldn't cost more than $20 to have 'em pressed on. I spent maybe 5 minutes doing it. Maybe. <img src="gr_images/icons/wink.gif" border="0">

What holds the axles in then?
