I’m restomoding a 92! I’m looking for a hi-quality carpet kit! Any suggestions!

Haven't kept pace with current suppliers but years ago Al Knoch Interiors (https://alknochinteriors.com/) was considered a gold standard.  Toured Mid America Motorworks (https://www.mamotorworks.com/corvette) production facility at the C3VR Members Gathering held there back in 2011.  Don't know if they're still manufacturing their own brand.  Several of the other Corvette parts houses sold interiors from the same vendor but I'm sorry I don't recall their name.

I replaced the carpet in my '93 C4 in the spring of 2020, using the "Mass-Backed" set sourced from Mid-America Motorworks, and it turned out fine.  But if you're going through all the work of a carpet replacement I'd strongly recommend adding a layer of sound-deadening material underneath.  I used a pre-cut set of insulation material also offered through MAMO, and it's made for a much quieter ride!
