WIW - 71 C-10 250ci 4spd short step

[sofla71chev]

I have to sell my project truck and i have no idea what a reasonable asking price is. I will probably be putting an ad up on this sites for sale section along with craigslist, and maybe some local free papers. I prefer not to seperate it and the parts for it. Pictures of it can be seen on my old build post http://67-72chevytrucks.com/vboard/s...d.php?t=263324 Any suggestions will help, Thanks.
I started writing the ad already and this is what I have got:

1971 Chevrolet C-10 Shortbed Stepside with a 250ci straight 6 and 4 speed on the floor transmission. Engine runs good, transmission does grind some gears, but all the gears work. I was driving this occasionally back and forth to work, till I found out that the rear trailing arm crossmember is cracked and probably not so safe to drive on, which I am including. It does have rust in the typical rocker/floor area and some surface body rust. I have over $2000 of brand new parts to fix this truck up that will come with it. I already installed new front pads, rotors and calipers. And converted from manual to power brakes. It has a new windshield.
Some of the other parts I have are:
Outer rocker panels
Inner rocker panels
Front floor pans
R/F Cab support
10 piece weather strip kit
Classic Performance Products drop center trailing arm cross member # 6372LDL
Classic Performance Products deluxe adjustable rear track arm kit # 6572DTBK
Classic Performance Products rear shock relocator kit # 6372SRK
Classic Performance Products trailing arm reinforcement kit # 6072TARK
Air Ride Technologies CoolRide rear air suspension kit with shocks # ARR21800
