The second link cut off the last part of your link.ï¿½ Cut/Paste got me to the other to compare.ï¿½

I'll confess, I stared for a while and I think I see the diff.ï¿½ Cheap one is suffix -K1 and the more expensive is suffix -K2.

Both say they fit the same vehicles.ï¿½ The difference I see is the more expensive kit has "period correct hangers."ï¿½ Look close and you'll see the diff (the cheaper kit has generic hangers).ï¿½

BTW I'm using generic hangers on mine.ï¿½ They'll need a plate or large washer up top of the rubber dampener to anchor it properly and keep it from tearing loose when attaching to the frame.ï¿½

I'd call Walck's and ask if the cheaper version is as pictured or if the hangers have hardware to attach to the frame, i.e are they complete generic hangers?ï¿½ Then you'll know.

FWIW, the Parts Manual (PM) I have says, the bolts are 5/16" x 24 and vary from 3/4" to 1" in length (just get all 1").ï¿½ So to have a complete set, you'd need bolts, flat washer, lock washer (and also a large fender washer) and finally a nut for each.

There may be a bit of fabricating needed.ï¿½ You may have remnants of hangers still on your jeep that can be reused.

What I do see missing on both is an additional hanger on the tail pipe that attaches to the spare tire reinforcement under the wheel well.ï¿½ Since I used generic hangers, it was no big deal to add that.ï¿½ ï¿½Mine has hangers front and rear of the muffler and the tail pipe is pretty stiff BUT the PM shows a hanger there.
