It's been almost 20 years old since Monogram released it's '93 Chevy S-10 standard cab shortbed 4x2 pickup, but this kit has held up very well, mostly due to the kits' excellent design and engineering. This kit was a companion to the '91 GMC Syclone released by Revell in 1992 (reviewed here: http://www.modelcars...0279&hl=syclone) , so there is some parts sharing, just like on the real Chevy S-10 and GMC S-15 pickups. Two other versions of the S-10 kit include the "Waverider" custom, kit #2438, issued in 1994 and molded in metallic green, and the Lowrider 3'n 1, kit #85-2569 from 1999, which contained parts to build any of the three variations.
To be totally honest, I have never built any of the S-10 versions of this kit, but I have built the Syclone, and I recall it going together without any issues, and the parts fit was excellent, so I would expect the S-10s to be a tad easier, since the engine compartment and front suspension/drivetrain is a bit less complicated. My only complaints with the stock S-series kit are the "missing" Cameo body cladding pieces, and the Goodyear VR50 tires, which would've been too lo-pro for a stock '93. There is plenty of detail present to make a very nice looking model when completed, and seeing as this kit was released during the high point of the Revell-Monogram period, it's no surprise this is still a great kit almost twenty years after it was first released.
The only four aftermarket resin parts I'm aware of for use with this kit are:
1) All American Model's out-of-production 2-door Blazer body: http://www.rocketfin...uct.cfm?id=2350
2) VCG Resins' '84 Blazer body, which is still a WIP: http://vcgresin.atspace.com/
3) Perry's Resin's extended cab ("Club Cab Conversion"), which I think is also OOP, but included the cab, interior tub, and chassis.
4) Perry's Resin's '82-84(?) grille conversion
