Kris, congrats.
A guy I've met a few times locally has a blazer in that body style... he hangs out over on 67-72chevytrucks.com . A lot of the guys over there have those, might be a good palce for you to look for information... but you will have to look for it as they keep having issues with their search functions over there.
This is his(NuBomb) profile over there:
