1970 cst10 swb 2wd

[wnc mountain]

Considering selling my 70 in order to fund a blazer build. May not be worth selling if I can't get enough for it. Just don't know the value of my rig. Be honest please!
The details.
Factory Bucket seats. 350/3 on the tree.
Added power steering. ECE 2/4 drop with shock relocation brackets and adjustable track bar. ECE front sway bar. Tires are about two years old. Added a cater/edelbrock 750 carb, valve covers and air cleaner. Have all the original stuff down to the riser tube. Long tube headers with 2.5 exhaust and flows. Hidden hitch.
I bought the truck about 12 years ago from a man that bought it in 1971. It has stayed indoors since I have owned it. In the 12 years I have only driven it about 6-7K miles. The motor does need new seals all around, leaks oil. I installed new vinyl on the drives seat along with new foam. I have a new skin for the passenger seat but the original is in good shape. New dash pad also.
