Fair price for an 8 3/4 housing with axels?

Really!!!
I went to look at an 8.75 that was on CL in a little town in the mtns... when I got there it I found it was still attached to a car that was buried in snow. When I looked inside I saw it was a 4 speed car! I checked the VIN and found it was a 4sp 340 Swinger.
I knew if I pulled the rear end they would scrap it.... so I offered 1200 and bought the whole car minus engine
