    Looking into replacing the rubber puck style body mounts on the wagon...I believe the original set-up was with the rubber pucks directly between the body and frame...but I was wondering about sandwiching the rubber puck with flat washers on each side to possibly help with long term deformation? Good idea? bad? Will it create too much stress at the edge of the washer on the bottom of the body? Maybe just a waste of money for 28 washers (14 mounts)?

    Cant hurt, I'd suggest body washers as big as the puck though.

    yes - I should have specified some fender washers, although the pucks are somewhat surprisingly small diameter....also was suggested to make sure the washer hole be a a couple size larger than the actual bolt to ensure no issues with restricting differential movement/vibration....

    So here is comparison of the what is coming out vs what is going in....

    the replacements are the reported correct 7/8" thick and 2" in diameter....the ones coming out are more like 1/2" thick and 2.25" diameter....I am happy to get a bit of body 'lift' from these. Not sure if the ones coming out were 7/8" thick at some point and have squeezed down and out, or if someone used different pucks at some point (I believe earlier trucks and wagons used something closer to what is coming out, so maybe that is where they came from). Inspecting the body mounts on the frame and body, with the 2" diameter puck, they are completely covered on the top and bottom with the mounts, so not sure there is any need for the additional washers sandwiching the puck - just the OEM washers for the bolt head and nut. Additionally, I am having some 'fiddly' issues and the body is not trivial to lift up just enough to slide the pucks, so I going with just the pucks for now....maybe after I get them all in, I could try and redo do them and slide the washers in, but for now, it doesn't seem needed or worth it....

    In the past, I have used actual hockey pucks for Wagon body mounts. They are similar in size, but are harder rubber. I bought them as cases od 24 pieces. They were a bit challenging to drill a clean hole though, but worked quite well.

    same here...it was the budget lift for my YJ....I was from FL so didn't know much about hockey, but went to undergrad at Colorado College which is a big D1 hockey school (back then they were competing for national championships with Michigan and N Dakota etc - they struggled a lot more of late) and my roommate was a recreational hockey player - he used to pluck a puck or two when there was open ice/intramurals and that was the 'budget' lift...
    I am still debating trying to add some additional washers around the 'pucks', but that would require longer bolts and thus all new hardware....sounds cheap, but I am not really in the market for another $20 in hardware at the moment...Start work a week from today so hopefully the cash flow will start to balance out...

    So here is a comparison with one side with the new mounts, and one side still with the old (hopefully finishing this off today)....
    With the old mounts, the body floor channels were basically sitting on the frame rails:

    With the new mounts, the body floor channels have some clearance above the frame rails which should work a lot better...

    My motor mounts are some of my old pucks.
    The blue kid pucks are softer than the black adult pucks.
    Definitely need a drill press or lathe the bore them. A few random little holes can soften up an adult puck but it's not worth the time.

    Where'd you get the thick rubber mounts?

    Walcks...they have two thicknesses based on year and model. I got the 7/8" thick which is the OEM thickness for later wagons.

    I wouldn't use hockey pucks, but that's just me. I know a couple guys that did that back in my younger years, and the pucks ended up splitting, and the cab came off the pickup..... Luckily none of them were at high speed or anything, but they didn't hold up real well.

    If the puck is drilled and the bolt is from hole in metal thru puck to hole in metal I don't see how the cab could come off without the nuts coming off the bolts.
    I also don't understand why there isn't any rubber cushion for the pull of the bolt on the body since it's a give and take sort of thing.

    Pucks are hard but I am skeptical that they would just split I had to use an angle grinder to split a puck after drilling a line of holes to try to break it in half for a smaller mount.

    Used Canadian made pucks. They are super quality rubber, never seen them deteriorate or split. Actually, pucks are too firm, but back when I used them, there weren't many vendors for Jeep parts other than the Sears Jeep/Scout catalog.

    I can't vouch for the quality of the hardware that was used, this was back in high school, but I'm assuming the leverage of the overlong fasteners cause something to fail, be it the cab floor, or the hardware itself was cranked over due to the fastener being too long and no longer torqued down, once the puck split and squeezed out of connection. I also don't know the source of the hockey pucks that were used. They could have been substandard quality. It also could be due to the guys that did these cheap body lifts being morons.

    I don't know. I just know that I saw it happen three times, twice on squarebody chevies, and once on a dentside ford.

    I wouldn't do it. But that's me. I'm not a fan of body lifts in the first place.
