That does not look like what I used..... I do have the part number, just not with me. I won't be able to get to it for a week. HERE IT IS..... Granger part # 5GB11.

Keep searching Granger. If I recall, they were arbor shims and were high quality. Not just washers. They were a perfect fit.

Determine the thickness that you need for a shim, and then just cut that same amount off the face of the axle nut.

Keep searching Granger. If I recall, they were considered shims and were high quality. Not just washers. They were a perfect fit.

Ahh, maybe an Arbor Shim! https://www.grainger.com/product/PRE...rchQuery=5GA99

This will be helpful for those that follow....

For us proletariat lacking lathes, you don't need to turn down the nut face. Discard the outer .250 washer and use three of the .062 arbor shims from the package of 10. Crude, but works.

I've been noodling the same problem on my -7. This is the answer.

In the never again file, it's always bugged me that Van's has you build up the interior of the pant for reinforcement - which throws off all those carefully positioned holes in the bracket and spacing with the disc. Next build will have the reinforcement on the outside of the pant and blended in. The wind will never know.

This seems like it would defeat the felt packing in pretty short order? The felt (dirt guard) likes a nice smooth surface to ride on.

I'm using the Matco brake set Van's supplied - maybe still does - four years ago. The Matco bearings have an integrated soft plastic seal, no felts required, ergo no reliance on a smooth OD running surface. Good point, though. Main concern I have is the low carbon steel shims will quickly corrode.

Is there any reason this rapco disc upgrade would not be compatible with the Matco wheels that Vans is sending with the RV7A/9A kits these days?

I have Matco wheels and brakes, and would love to try the thick disc upgrade.
