Every 4x4 S-10 or Blazer comes with skid plates. The crew cab is the first 4x4 model released with no skid plates. Since the crew cab sits on the same frame as the extended cabs do, all the skid plates off other S-10's will fit on our trucks.

Brule has researched and gathered all the information for us. He helped me find and put on all my plates.

There are 4 skid plates: Front, Engine or Front Differential, Transfer Case, Gas Tank. You can get the plates from other S-10 Ext. Cab 4x4's or you can order them from the dealer or from www.gmpartsdirect.com

Front:
Since Gm put a plastic front shield on their crew cabs, they left it up to the buyer to actually equip the truck with protection. And of course you can't just buy any shield because of the remote oil filter door.

The GM part number 1515-5700 SHIELD. It is available through Chuck Hutton Chevrolet for $79.08. You can order it straight off the web at http://www.gmpart.com.

Engine:
Here's the complete list from the dealer of what all you will need besides the plate. (I have not personally ordered any of these so I cannot confirm they are indeed the right parts, but they are straight off the GM parts break down at the dealer)

Qty. needed-1 Front Diff. Shield # 15038017 list $65
Qty. needed-2 Bracket (should include bolt and plate) # 15561150 list $12.12 ea.
Qty. needed-4 Torx Bolt # 14062942 list $6.30 ea.
Qty. needed-4 Plastic washer #15650965 list $0.67 ea.
Qty. needed-4 spring washer # 4722812 list $4.41
(You may also need some nuts , available cheaper at a hardware store)

The front of the plate installs into the cross member already on the truck. The back of the plate bolts into brackets that have to be installed. The bracket installation was easy. Just take the 2 bolts out of their location. The passenger side bolt will barely fit with the bracket added.

Gas Tank:
The shield that I used was off of an 1986 ext. cab S-10. The only thing I had to order was a bracket that supports the front of the shield.
The part number for the fuel tank shield is 12495667 - GMpartsdirect.com price was $91.56
The bracket part number is: 15960535

Using the first gen parts there is also a support bar that will need to be modified just a little to work. I took the bar and I cut about 2.5" off one end and flattened it approx.. 1.5" at 90* to the other end, then bend it to 45* and drill a 3/8 hole.That's kind of a rough description.

So here are the list of parts that are needed:
The gas tank sheild & bolts,nuts..-off any s-10 4x4 ext. cab
The bracket-order from GM
The modified support bar-off any S-10 4x4 ext cab
