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.


3.23 is a great gear.. find out what case you have. easy enough.. then take a pic of the sure grip unit..

have seen 4.10 sure grips going for good money..
