I've owned three different ZR2 blazers and I loved them all. Such a fun and useful little truck. I wish you could still get new vehicles like that. Imagine how fun a ZR2 blazer would be with a 4.8L LS V8 engine and a 6 speed transmission (automatic, but also a whole other level of fun with a 6 speed manual!)
But sorry I don't have any parts like that left so I can't help you there. Unless you also want 99+ style rearview mirrors or an instrument cluster.
