I have a disassembled 72 rear end that has 3.73 gears.axles are good and breaks are still on there.everything is intact.Was going to use it but I need a 69-70 grille..would consirder a 71-72 grille if you have one to trade.

Re: WTB - Need a good posi unit for a 3.73...
 

I have a 3:08 Posi complete rear.

Re: WTB - Need a good posi unit for a 3.73...
 

King - Unfortunately I don't have any grills and all I really need is the posi unit to put in my 3.73 rearend. If you would be willing to separate the posi unit, let me know how much.

Gene - All I really need is the posi unit. I don't think the 3.08 carrier will work with 3.73 gears, but I'm not positive. No pun intended, :D.

Re: WTB - Need a good posi unit for a 3.73...
 

I have a rear end with a 3.73 gear set and a posi. 5 lug axles. Completely rebuilt. All new bearings and seals, etc. Painted high gloss black with Por-15. I would possibly trade for a rebuilt 3.08 posi rear axle in same condition if you were interested. If I can find a good used turbo 400 I'de be better off with the 3.08 anyway. LMK if interested.

I've got a 3.08 posi with 5 lug. Are you going to Atlanta any time soon? Or you can come down and buy my 50th SWB BB and take it with you....:D.

Re: WTB - Need a good posi unit for a 3.73...
 

Dont beleive I'll be going to Atlanta anytime soon. I'd love to have a 50th but I should probably finish my 72 Big Block Super Cheyenne first. Is your 3.08 rear rebuilt, painted, etc? May be able to meet you halfway if you had a couple short fleet bedsides you could make me a good deal on.:D

Re: WTB - Need a good posi unit for a 3.73...
 

Bump. Anyone have just an Eaton posi unit?

Re: WTB - Need a good posi unit for a 3.73...
 

I just bought a brand new eaton posi unit for less than $400 at a local place called drivrline express.

Re: WTB - Need a good posi unit for a 3.73...
 

Did it come with an install kit? Do you have a part #? I was trying to find a good used one, but this may be the way to go. Thanks for the information. Making any progress on your big block truck? I've got to make a decision on whether I'm going to continue building my 50th BB SWB pretty soon. If I don't I'll have a bunch of the hard to find BB stuff for sale. TTYL.

Re: WTB - Need a good posi unit for a 3.73...
 

I don't know if it came with a kit or not. I am not even going to try to attempt to install it myself, I am going to let my rearend guy do it. I will be out at the shop in a bit and will try to get a part #.

My project truck or at least the body has been at the paint shop for 19 nonths (16 months longer that he said it would):lol:, but I am very close to getting my little swb survivor in daily driving condition.

I can always use BB stuff, I really really need a BB heat riser if you have one of those.....Jason

i have a posi rear 3.73 still in rear i bought it to put it my blazer never got around to it but i an in maryland

Re: WTB - Need a good posi unit for a 3.73...
 

Glad to hear your making progress on your truck. The part number would be great when you get chance. I've got an NOS heat tube (no sticker), perfect heat riser, passenger side heat shield, pulleys, complete bracket setup (a/c, ps, alt), fan shroud, clutch fan, 402/TH400.....pretty much everything to put together a nice BB truck. The pictures of your motor and chassis is what set me off on this journey.....:lol: I found this LWB 68 50th factory BB/AC truck to do the build with, but I've got to many projects.... Here's a link to what I'm doing with it:

What shape is it in and how much? Any pictures?

Re: WTB - Need a good posi unit for a 3.73...
 

Rob, I'm going to Maryland (Easton) in September. May be able to get it closer to ya. Could bring it back to NC. LMK

Re: WTB - Need a good posi unit for a 3.73...
 

Here is that part # Q19556-010. And that is the correct one for a 3.73

So you are not in NM anymore? A BB SWB 50th would be pretty hard to beat.

I really don't need BB stuff, I just want it:lol:I have a shelf full of stuff, but i do need the BB tube if you ever get a spare..............Jason

Re: WTB - Need a good posi unit for a 3.73...
 

Thanks for the offer, I'll let you know.

We moved back to FL a week ago. Hopefully someone will buy the 50th and do it correctly. I'll keep my eye out for another tube or let you know if I decide to part everything. Thanks again for the information.

Re: WTB - Need a good posi unit for a 3.73...
 

Cool, let me know.

Re: WTB - Need a good posi unit for a 3.73...
 

I have a clutch type ( eaton )posi with 3.08 gears now 250.00 + shipping

Re: WTB - Need a good posi unit for a 3.73...
 

Do you know the condition? Will you sell without the gears?

Re: WTB - Need a good posi unit for a 3.73...
 

Rob,

did you see this one???...http://67-72chevytrucks.com/vboard/s...d.php?t=357493

Re: WTB - Need a good posi unit for a 3.73...
 

The 3.08 posi will not work with 3.73 gears. Instead of buying a full posi, I bought a powertrax lock-right, I think it's part# 1910. The advantage is that you can do it yourself with regular hand tools and no installation kit. Mine went in ok, but I haven't driven it yet because the truck is still being put back together.

Here's an article, and they are available all over the place.

Re: WTB - Need a good posi unit for a 3.73...
 

Thanks for the info HGS. Do you think it will hold up to over 600 hp/torque?

Re: WTB - Need a good posi unit for a 3.73...
 

No, they will not. I broke 2 of them with a stock zz4 and 275/60r15 tires.

Re: WTB - Need a good posi unit for a 3.73...
 

Probably not, but depends how you drive it of course.:burnout:

I'm not sure the 12 bolt with standard axles will take that abuse for very long. You may need to upgrade the axles too.
