Bar end cab mounts.......

the whole polyurethan body mounts, are, in my opinion, harsh ride.. b/c its basically solidly mounting the truck to the frame, they dont have the give you'd want.. i'd get some 3x4 C channel.. cut the 3" side at an angle, cut a hole out of the 4" top piece to hold the stock bushing and go that way... or go 2x4 if you dont need a deep angle.

I'd probably go with some Energy Suspension poly bodymounts. The ones I've seen, where softer and more pliable than the link ends. Those may be too stiff.

I used the energy suspension bushings and 1 1/2 tubing for my cab mounts..I have pics in my profile under the 2002 fullsize
