hi everyone. i recently aquired a 1968 gmc 910 for FREE!! it has a inline 6 engine in it. i am new to this whole restoring/rebuilding old cars and trucks thing.
a few questions i have: is a gmc 910 worth restoring?
are they rare or worth anything?
is there anything i should look out for with these trucks
or engines?
thanks
