Sure Grip Rearend Value Question
I currently have a 8 3/4 posi rearend with 4:11 gears in my 70 dart. I purchased a new rearend with 3:23's in it to do a swap. What is a fair price to sell my old, good working condition 4:11 posi rearend for? Axles not included.
wes beem - dont worry about calling it a "posi", these people all mean well and are really good sources of info. Just dont ever do it again...LOL! If you want a number for a good working "sure grip" unit with 4.10 ratio it will sell $400-450.00 all day long.
But you really need to verify the ratio on the ring gear (stamped in to it) and in the case like jerkyboy showed you. The case has the number we all are looking for cast into the drivers side of the lower pinion area.
The last 3 digits are what most look for. 742, 741 or 489 is the number they are referencing. This will tell pinion size and style.
Is it large yoke or small yoke
Then, what style is the "locking portion" or "posi" as you call it. Some are cone styles and some are clutch styles. I wish I had pictures to show you but if you research there are pictures on Google or even
on here thru search.
When you swap it out, take some photos, especially of the wear pattern on the ring gear. Let us know if there was anything in the oil and how much play there is and the more info the faster it will sell.
Remember shipping isn't free for a heavy unit like that.
Good luck,
Joe
