Where are people finding the bushing stock for W21-12? Its 3/16" ID x 5/16" OD steel bushing stock. I am finding all kinds of sizes, just not the one I need.
Thanks,
Mike

If you got the kit, it comes with it (I mistakenly was looking in the bags of hardware from Wicks).
For scratch building, I'm not sure.

For scratch building, use 4130 seamless tubing.

For scratch building you can also order the bushings from Sonex.
$2.00
SNX-W21-12 Pivot Bushing
I ordered mine from Sonex and then forgot about them on the shelf. Spent time spinning my wheels trying to figure out a solution
