Cab mounts - part numbers?

[Dual quad]

I want to replace only the upper cushions of my 4 cab mounts and 2 rad mounts. GM-Parts-Direct lists the part numbers and descriptions below, but I'm not sure which ones I need, and if the ones I need are all the same. Any help is appreciated.

GM PART # 3909351
BODY MOUNT CUSHION PANEL TRUCK/SUBURBAN

GM PART # 3951798
UPPER MOUNT CAB MOUNT

GM PART # 3953135
LOWER MOUNT 2 WHEELDRIVE

GM PART # 3957829
BODY MOUNT CUSHION REAR CAB MOUNTS

I don't know the GM part numbers, but my local Chevy dealer parts dept wanted about $300 for all the bushings for my K10 burb. And that's just the rubber!

GMC Pauls, for one, sells rubber cab mounts. They had my burb mounts, again minus hardware, for $184 +shp. Still expensive, but not dealer gouging. Cab mounts cost much less. Here's theircab mount page.

Thanks for the feedback 4X4. Ya, the 4 wheel drive kits are expensive. The GM-Parts-Direct cushions are reasonably cheap, so I think I may order 2 of each to see what I come up with.
