I agree its a great kit, I've order a bunch of them and bodies. Your buck tails are great too. Very impressed with quality of the wood, components, and instructions. Its clearly user error. It should be fool proof, just didn't want to ruin it after all the prep work: sanding, sealing, primer, base coat(s), scales, epoxy clear coats. The part in question was/is the a tail grommet spacer. I've never used/seen them before. My fault. Love the site Merry X-mas.
