Cheapest way to get posi

It's not even a guarantee in those models. And even in the ones that should have them, they may have been pirated.I've found them in lame-o Grandma cars but they usually had Granny gears too. At least in a sporty model you 'may' get a good ratio. But it's worth looking around, since by the time you buy a set of gears, a posi carrier, and have a competent shop set it up, you could have bought a great rear complete for far less. It's a lost skill setting up a rear, and worth knowing, but it must be done RIGHT or carnage will result.
Ya I have heard it can be really hard to do and get everything perfect and ya good point I'm just going to keep my eye out at junkyards and on Craigslist. I don't really care to much about the gears just as long as there not to low of a gear I daily drive mine do I want to maintain the best mpg possible
What gears are in there now? I have a 2:78 posi and I cruise at 2000 rpm at 55 mph. I think 3:08 and 3:23 are good ratios, not bad on the highway, yet peppy on the street.
I have 308s on a 225-60-16 tire and I am glad I didn't go any lower (higher number) I drive 65-75 mph and I am usually around 3 grand. I have to get a better radiator just from going with 308s I used to run around 160 now I an around 180-190 on the highway. I wouldn't go over a 3.42 if you have a 3 speed and hit any highways.
Ya that's my main driving is on the freeway at 65 I'm at about 2400 rpms I'm leaning toward not getting gears for that reason
Here's a neat calculator to figure out what gears you have without opening it up.http://www.wallaceracing.com/calcrgr.php
thanks for the info so basically if i got gears around 330 my rpms at 65mph it would go up around 500 so i guess if i went that route i would drive at 60 haha
Is this a good enough picture to tell if it's a posi this is the picture the guy sent me and I can't tell any help is appreciated doesn't the housing have to be rotated a little more to tell?
With that pic I'd say no, because I can't see the clutches or spring/s. And on second look, it's a non-posi case, wrong shape for a posi. See the lip of the ring gear where it bolts to the carrier flange? The tooth counts should be stamped on that ring. Here is a picture of a posi case. Much different than what you are showing. Smells fishy to me.
