1990's full size Chevy truck accessories

Looking for a couple things. I have been wanting to find a kit to relocate the spare tire to the back of the truck by the tailgate on a swingout like they have on SUV's like the Blazer, but havent found many options. Lots of inside the bed stuff, an the under the tailgate factory options don't seem to hold up to the weight of oversized tires. Also, Has anyone found a viable snorkle kit for 90's era Chevy trucks yet?
