Body mounting hardware

[biketopia]

So I'm hoping to get around to mounting my cab and core support to my chassis in the coming weeks. I'm digging through my parts stash of new and used stuff. I'm planning to install these bushings, https://static.atechmotorsports.com/.../ens-17016.pdf I can source new bolts locally and have the specs on them, but I can't seem to locate the factory washers it speaks of in the directions. Are they just a thick washer or do I need the specific factory style ones and are they available anywhere?

The body mount washers are close to the same diameter as the bushings they fit against and are approx. 1/8" thick. The core support washers are thinner but still thicker than most hardware store washers. Try ACE Hardware, Fastenall, (if you have one in your area), or as last resort a farm store. (check in the farm equipment area of the store for the bigger washers)

Are you sure you want urethane bushings?
Different is not always better.

95% sure. This will be lowered on coil-overs, big engine, corner carving type truck, even though it is a long bed.

Thanks, that's what I thought they were. I have a vendor I can work with on that type of hardware if I can get it at my local nut & bolt place. Specifically it calls out a washer with a square hole in the front cab location, is there an actual requirement for that?

[Dashman]

Front cab or radiator support location? It's a square washer with a square hole because the radiator support body mount uses a carriage bolt. It restrains it from turning while the nut is tightened. You could access a hex head bolt with some long extensions, then you wouldn't need a square washer with a square hole. I don't recall there being a square hole washer at either cab mount location.

The instructions indicate front cab, but makes a lot of sense for the radiator support though.

How does body mount bushing help cornering?

Keep the rubber just in case you get tired of the tighter connection to small road vibration. Just be true to yourself as to the amount of benefit and how much you actually use this benefit to the compromise in daily ride, if you intend to continue to drive on street. I get it. You want the best performance possible. Problem is you end up giving up the street use at some point.
True story. Bought a rather rare BMW in 2003 and HPDE tracking shortly after acquiring. By 2006, I replace with similar model in every way except, the rare for the model, (S54 Mcoupe) S54 motor. I stripped and caged the new one. Aluminum bushings and heim joint suspension points with +3 inch track. Finally a Jerico dog box and LS. It just never ends and of course this car will never see a street again.
Goood luck with the mods.

I'm not concerned with NVH and gentle ride characteristics that most seem to be after when recommending rubber over polly.

Ohh I know the rabbit hole all too well. Bought a 95 Camaro with a blown LT1 to have fun little burn out car, nothing serous. Started with a 350 and mild cam & headers. Ended with it caged, full tubular suspension, solid motor mounts, stripped interior, etc. It had it's quirks for sure but I still drove it regularly. Was a fairly nice ride on the street too, no obnoxious drone from 55-75. When I lived in a neighborhood the neighbors didn't like the 5500 stall at 530am leaving for work through our hilly neighborhood. Pulled the drivetrain and it will be going in the truck with all the no limit goodies.

At least the truck frame won't twist like the Camero's. LOL
You'll feel the weight difference though.
Condolences to your bank account.
