Question Does anybody have a pic of there rear end

[athoose]

Are the bolts SAE or metric. If it's a 9 inch you can't slip a socket and wrench over the bottom two bolts, only an 8 inch.

Oh you should see/feel some raised casting numbers like C90E.

just looking at the pics I posted before you can see you could slip a wrench over the bottom 2.

here are pics of my 73s rear diff. these are the best i can get without rolling around in the mud. as far as i can tell its the stock rear diff.

 

 

 

 

hmmmm... looks like i may have a leaky vent.

I just wanted to tell everybody thanks for the pics up to this point. I know its a pain in the "rear end" to go take pics under the truck.

 

Well your pics tell me its not a Datsun rear end at least not 73. The welds on Datsuns come all the way up to the pumpkin. This one they Y. Also the front member is shorter on mine than all of the Datsuns I have seen thus far. Another thing is the rear indent is deeper than Datsuns to. Oh bother It looks like I may have to take the damn thing apart to figure it out. I may just wait to go down to a old car shop here and see if they can help me on it.

 

It has 2 tabs seen in red line like a Datsun but the shorter nose and the 3rd member bulge is whats strange. Also it is flat all the way around the outside of the diff where the bolts go. Datsuns so far have the tabs coming out the edge.

 

Doesnt look like Toyota. Just found a total write up on all 4x4 rear diffs. Basiclly 3 different ones through out the years.

quote from this write up. "All pre-'95 4-cylinder 4wd mini-trucks & 4Runners use the Toyota 8" 2-pinion differential front and rear (except turbo models). This is known as the "4cyl diff." This diff is by far the most common diff in older Toyotas"

might be a mazda rearend? my dad had an 81 courier and he put an early mazda truck rearend under it. he said the early ones were stronger. maybe theyre strong enough for a v8?

Sounds like most of the Mazda's use a ford rear end 8.8" or a rear covered rear end that is a 5 or 6 lug patteren.

 

I dont know at this point. I think Im just going to take to this shop when its done. Maybe I can jack it up and look for some numbers. I was wanting to take it to the track and make a couple of passes but I dont want to if I have a non-posi and if I granade this rear end I dont want to put the truck into the wall. Will see....and the search continues.....
