Welcome to the site!
Looks like a good, hopefully easy, project. I believe you can find a lot of help in here.
Besides getting some technical help from
The Shops Area, you may want to stop by the Parking Lot where the
60 - 66 trucks hang. Looking for those parts, they may be able to help, as well as
the Swap Meet.
And for fun: we have a
Stovebolt Volunteer Fire Depart in the Parking Lot under Big Bolts. Ah, yes ...
Big Bolts, another active group.
Bringing another GMC into the fold is exciting to see!
And I personally have to say, it's always good to have an Alabama fan here. Roll Tide! 
We'll see you in the forums.
