8-3/4" Purchase Questions

Help me out with the pricing:

Base B, E or C body rear end (non sure grip) = $250.00 (I found a couple at this price)
Dr. Diff 8-3/4" Clutch Type Sure-Grip ("Powr-lok") = $395.00 (out of stock)
Dr. Diff Axle Pkg Stock Length Mopar 5 X 4-1/2" Bolt Pattern = $295.00
Narrow rear end = $250-$400 (gotta think in my area, it will be more like $500)
Brake job, bearings, lube, seals, etc. = $200 or more
Total = $1390.00 to $1540.00

Not adding up to less than $1000.00. Did I misinterpret what you meant?
